We highly recommend that the pixel dimensions are less than 1200 pixels on the longest side (if a horizontal painting), but over 500 pixels on the shortest side (if a vertical painting). This is so the entire image can be viewed on a computer screen by the judge. Don't worry about dpi or "dots per inch" because the image will automatically become whatever the computer screen displays, usually 72 dpi or 96 dpi, after it is uploaded. The file size limit is 2 Megabytes, or 2 MB.
Your image may look "pixelated" if it's too compressed or too small in the first place. Please email us a replacement image if you need help with fixing it. If you didn't start out with a sharp, high quality image, or if you tried to enlarge an image that is just too small to begin with, it will be pixelated and that could hurt your chances of winning. Please ask for help if you need it!
The "pop-up" version of the image of your painting shows the entire work, whether vertical or horizontal, and there is an arrow that can be clicked on to view parts of the painting close up. The pop-up version is only available when you click on the large photo of your painting when it's on its own page.
