Loading screen photo for Adobe app

I think you must be invited by Adobe's engineers to submit artwork that's used in apps.  And the artwork would have to meet that app's technical specifications (height, width, filesize & format).  This probably varies by app.

If you mean the splash screen of Adobe applications, they get mostly sourced from Behance. There is no known method to postulate for this.

I assume that Adobe selects images to use throughout their apps and systems from the more than 370 million assets in their Stock database which you can peruse here:

https://stock.adobe.com/search?search_type=usertyped

As @kglad indicated, you can become a stock contributor,, though I know of no way of specifically bringing a particular asset to Adobe's attention.

i know of no such location, but i'll move your post to stock contributors if you want to start offering your creations.

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
