Since you're posting self-contained images with captions, the <figure> and <figcaption> elements might be a good fit for the feed here

Also related to a11y - you don't need to duplicate the visible caption in the alt attribute. The caption is for information about the image, whereas alt is for describing the contents of the image. So e.g. the caption might be "my favourite pet Nick Cage", and the alt would be "legendary actor Nick Cage wearing a sick leather jacket with a confused look on his face". Unfortunately this does mean the alt has to be written by the uploader. In this situation it's probably fine to leave the alt empty.
