A template set is one image per size. Get the files right and the upload takes seconds.

Cover the sizes you need. Square (1:1), Landscape (1.9:1), Feed (4:5), Portrait (9:16), and Portrait 2:3. A set doesn’t have to cover all five. It only needs the sizes you’re building for.

PNG or JPEG, under 20MB each. Anything else is skipped.

Let the dimensions do the work. Adora reads each image’s aspect ratio to decide which size it belongs to, so filenames don’t matter. Export at the exact ratio; a little rounding is fine, but noticeably off-ratio images won’t be recognized.

Keep the creative area clear. Whatever sits behind your overlay shows through, so leave that region transparent.

Name the folder for the set. Put one set’s images in one folder and the folder name comes through as the set name.
