New Image Submission method

When it comes to submission of image in example the Daily Challenges, users should have the option to choose an image they published from the categorised collection.

For example I posted an image post of a cat, and I make a collection i created called "animals" to store the posts, and when I want to submit that to a Daily Challenge or other related things, it should give me an option to choose the "animals" collection where I can find and submit the image more easily, rather than having to scroll an unfiltered list if I have too many images and that particular images is quite far down
