Give the maker a clear view of the costume

Look for soft light and a visible face

Daylight from a window is often easier to work with than a bright lamp overhead. Choose a front-facing or nearly front-facing portrait. Avoid deep shadows over the eyes, sunglasses, hair across the face and aggressive filters that remove distinguishing detail.

Show the costume that went wrong

The homemade costume is the punchline, so pick a photo that shows it — the paper hat, the wrong colour, the last-minute fix. Head to toe is ideal if you have it. A phone photo of an old print is fine; crop out the album edges so only the child remains.

Use one subject per photo

One clear child in the frame keeps the identity unambiguous. Keep other people out of the crop and leave enough of the head visible to show the face. For a pet, use a sharp photo with visible eyes and coat markings.

Check the file before upload

Use JPG, PNG or WebP within the 10 MB limit shown in the tool. If a phone image uses another format, export a supported copy first. When signed in, choosing a photo starts preparation and upload; the browser corrects orientation and resizes large images. Signed-out selection is a local preview.

Check permission as carefully as sharpness

Use your own image or one of your own child. Children other than your own, public figures and celebrities are not permitted. Confirm that sharing the final video is also acceptable. If the result looks wrong, review the photo before spending another credit.
