Q: I volunteer for a rescue and I post the pet pictures. What is the best size for the pictures?
A: That's wonderful you volunteer for a rescue helping them like that!
Currently the maximum size for a pet listing photo to display is 336 wide x 329 high. Our photo uploading tool shrinks larger photos, as long as each photo file is not larger than 8MB. It is faster for you to upload photos that are smaller, around 200k is usually plenty big. See size tip below! If a photo is smaller than 336x329, it will display at actual size.
Photos used for the thumbnails that appear in search results will appear in the search results cropped into a square if they are not a square. (When someone clicks to see the pet's info, the photo appears uncropped.) The thumbnail is generated from the pet's 1st photo. If it is a horizontal, it crops off the sides to make a square. If it is a vertical, it crops off the top and bottom (equally from both) to make a square. So the best size is a 336x336 square, especially for the 1st photo.
Size Tip: If you don't have photo editing software to resize your photo to make it smaller, you can try this free online tool http://www191.lunapic.com/editor/
Thanks for your question!
