We say that you can “add up to 10,000 photos." But you can actually add more. If you do, the issue is that there won't be enough space in your mosaic to put all your small pictures. For example, if your mosaic is 100 tiles wide, and 100 tiles high, that gives you 10,000 spots to place your 10,000 photos. If you upload more than that, some of the pictures that don't match the colors of your big picture well, won't be used.

The eyes can get a bit tricky to render right in a mosaic. It's such an important feature, yet so small, so sometimes it’s hard to get it to look right. You can try couple of things when this happens. You can render your mosaic again and again until you get a version where the eyes look good. Or you can save your mosaic, and then replace the pictures in the eye area yourself manually. You can do this by clicking/tapping on the small picture you want to replace. Then clicking replace, and then selecting the new picture you want to replace it with.

Skin tone is another common issue that takes a little know how to get it right. There are 3 ways to make it better. First is, add more small pictures where the photo is a close-up face shot with the same skin tone as the big picture. This will allow those photos with the same skin tone to be used around the areas of the face and skin of the big picture. Second is, to use a third-party image editing software to tweak the colors of your big picture. Lastly, you can try to increase the colorization of your mosaic.

Color match is how well the colors of your small pictures match the colors of your big picture. So, for example, if you have a big picture of a person wearing a red shirt on green background, you want to have some small pictures where majority of the colors is red, green, and skin-colored. If you have that, then your color match will be high. However, if your small pictures are mostly blue in overall color, then your color match will be low. You want to get your color match as high as possible. Generally, 50% is good, but higher the better. It's also important to cover the full range of colors found in your big picture. It's possible that you have 50% or higher color match, but you don't have any red photos to match the red shirt. In such cases, adding some red photos will be more helpful than adding green or skin-colored photos to increase the color match even higher.

Yes. After saving your mosaic, you can add more photos to it, or remix it. Remixing creates a new version of the mosaic, which lets you compare multiple versions before making your purchase.

After saving your mosaic, on the zoomable mosaic viewer, click the photo you want to delete. Then click edit. Then click remove. Then update the mosaic by clicking update.

This is a really tough question that depends on your screen and the colors of your mosaic. All screens render colors slightly differently. And not all colors on screens can be printed in the exact same way on print. This is because screen is back-lit, while prints are not back-lit. Also, it's because screens rely on RGB (red, green, blue) colors to render colors, while prints rely on CMYK (cyan, magenta, yellow, black) colors to render colors. While printers use more than just the basic CMYK, it’s still impossible to render some colors like neon colors without using specific neon inks. So one of the things printing professionals do is to convert their image to CMYK colorspace to get an idea of what their image will look like before printing. Some people will create their work in CMYK to begin with, if they know that print is their ultimate goal. This is a feature that is on our long list of To Do's. To allow you to preview your mosaic in CMYK colorspace. However, until then, you can take a screenshot of your mosaic and open it in Photoshop and convert it to CMYK if you're really concerned. But you might not see much of a difference unless you’re using colors that is totally not doable in CMYK. This is also why we offer 100% satisfaction guarantee. However, you should understand that there’s nothing you can do to completely match your print to look exactly like your screen without some back-lighting and without restricting your colors. There is also nothing we can do about the quality of your mosaic. If your mosaic does not look good on screen, it's not going to look good on print. That's why you need to optimize your mosaic so that you like what you see on screen before you make your purchase.

After saving your mosaic, on the zoomable mosaic viewer, click the small picture you want to replace. Then click replace, and select the picture you want to replace it with. Then you'll see your new photo in place of the old one. Do it for all the photos you want to replace, and then finalize your edits. You must finalize it, or it will not be reflected on your download or print order.

You need to optimize your mosaic. We are not letting you order it because we know that either the small pictures are going to be too small for you to like it at certain print sizes, or that the white space surrounding the mosaic on a frame print will be too uneven for it to be pleasing.

Unfortunately, quality takes time. There is no way to expedite an order, so it best to plan and order ahead of time. If there is no time, then you can purchase the download and get it printed locally in person.

Make sure to double check the credit card number, and the security code on the back of your card. If all else fails, try paying with PayPal. You do not need a PayPal account, and you can use your credit card through PayPal. Sometimes you may need to call your credit card company if multiple failed attempts have been made already.

Sometimes, there is a delay with PayPal letting us know that your payment came through. If this is the case, wait a few minutes, and then the page should refresh itself to check again if it's been cleared. If it does not, contact us, and we can check the payment and approve your order manually.

Your mosaics are custom made and only valuable to you, so it does not make sense for you to return it as we cannot sell it to someone else. So we do not have a return policy, but we have a 100% satisfaction guarantee, where if you are not happy with your mosaic for any reason, we'll issue you a full refund. However you do need to destroy your mosaic and take and send pictures as proof prior to your refund. And if the reason for your refund was due to print issues or shipping issues, we also fully refund any expedited shipping cost. However, if the reason for your refund is that you simply just don't like it, then expedited shipping will not be refunded.

Depending on how it is being shipped, certain shipping carriers may take up to 48 hours before tracking information is updated on their site.

No, your mosaic is private by default. But you can make it Public or Shared. Public if you want the world to see your creation in our public gallery. Shared if you only want people with access to the link to your mosaic to view it.

Your mosaic privacy cannot be set to Private. It must be set to either Public or Shared in order for it to displayed embedded on your page.

Our mosaics are such high resolution that not all programs and devices can handle it. Professional imaging software like Photoshop will be able to open it, and most desktop programs can open it if your computer has enough RAM. Some programs will refuse to open it, while some will open it at lower resolution making it blurry. Some high end smartphones and tablets can handle it. If this happens, try opening it with different programs you have available. If everything fails, try dragging and dropping your download onto your web browser. Most modern up-to-date desktop web browsers are able to open our mosaic files at full resolution.

You can split your big picture into multiple pieces. Inception. Mosaics within mosaics. Tile multiple mosaics side by side.

You’ll be able to download it immediately after purchase.

Make sure to print your mosaic at full resolution. Do not let print shops downsample it. Check for brand of paper, and for brand and types of inks. Because not all papers and inks are created equal. You want pigmented inks. Branded papers and inks have reputations to uphold, they are much more likely to stand the test of time without fading.

You can, but mosaics are best when printed large. What you could do is, use an image splicing software to split your photo mosaic into multiple pieces so that you can print it. And then put the prints next to each other.

You can, but beware that the quality of the print will not be as high.

You can at some online print shops, but you won’t be able to at some others. And quality varies wildly. Some might not be able to accept the mosaic images at full resolution.

After purchase, just below your download button, there are download links for lower resolutions. Use those links to download lower resolution versions as necessary. Use the highest resolution possible for printing whenever possible for maximum sharpness.

DPI (dots per inches) metadata of the download is set to the default of 72 dpi. Do not be confused by this number. 72 dpi is the DPI of a typical computer monitor, and so image files that are bound for computers are automatically set to this DPI. This is just a meaningless metadata that automatically gets set. We cannot set it for you, because we do not know how large you will print your mosaic. Your image resolution is fixed. The actual DPI is determined when you print it. For example, if you have a 10,000 x 10,000 resolution image, and you print it 10 inches by 10 inches, then the DPI is 1000. But if your print is 20 inches by 20 inches, then the DPI is 500. The formula is to divide the image resolution by the print size.

Megapixels and megabytes are two different things. Megapixels is the measure of number of pixels an image has, while megabytes is a measure of the file size.
