Image guidelinesUploaded images must be:
- JPEG format (with the extension .jpg)
- less than 4000 pixels in the longest direction
- less than 6 MB (6000 KB) in size
For the best results, images should be:
- around 3000 - 4000 pixels in the longest direction
- less than 4 MB (4000 KB) in size
- exported using a program like PhotoShop, Apple Photos, iPhoto or Apple Preview.
Does color profile matter?
Yes. Images with an sRGB color profile will display more accurately in a browser. Most JPEG images are in sRGB format. And, if they are not sRGB color profile, exporting the images from PhotoShop or Apple Photos should fix this.
Does DPI matter?
Not really. This is because the DPI will be optimized for the best screen resolution upon upload.
