REST API Option to List by Posts (with Single Cover Image per Post)

[wyxos]

Issue:
The /images endpoint returns individual images, and since each post can contain up to 20 similar images, paginated results often include multiple variations from the same post. This leads to repetitive listings.

Suggestion:
Add an endpoint (e.g. /posts or /images/by-post) that returns one image per post — ideally the cover or first image.
Response could include:

post_id

cover_image_url

title

username

tags

Reasoning:
This would make listings more varied and efficient to browse or display, especially in galleries or explore pages.
