Sometimes I would like to illustrate a post with an image, that I know I did already use in another post. But I cannot remember the topic. I also do not remember when, so a bit involved searching the local files, it I even have the picture here and not trashed it.
A list of images uploaded by user or self would help.
I guess this extension would add this functionality: User Portfolio - Theme component - Discourse Meta
Example use here: topic list thumbnails example - Theme Creator
Try Search results for '@Hungerburg with:images' - OpenStreetMap Community Forum - though it seems the images aren’t viewable without opening each post…
