This version fixes the disappearing image problem by detecting your `sb_channels` columns and saving the uploaded URL into the matching supported image field.
`banner_url`, `cover_url`, `image_url`, `thumbnail_url`, or `metadata`.
`avatar_url`, `logo_url`, `profile_image_url`, or `metadata`.
If a real channel image is saved, it no longer shows the first movie image.
Single Play = Player 1. Channel Play All = Player 2.
Use image uploaders, then Save Channel. The debug box will show exactly which column saved the image URL.
Upload, Save Channel, refresh, banner remains.
Upload, Save Channel, refresh, avatar remains.
Edit channel again and values remain filled.
Channel video management still works.
Upload image first, then Save Channel to store the generated URL.
