Does anyone who's familiar with these types of things know how to add images on your profile? You know, how some profiles have a gallery like setting with the images?

I would do them myself, but then again I don't want to accidentally upload "duplicate" ones like I did before which my naivety I don't know how to upload images without doing that or if there's any option to begin with.

I would appreciate so much if those are an expert at it, I don't know much about how to edit correctly on this wiki like a lot of you do besides posting blogs, editing my plain profile, commenting on things you know, basic things I can do. I really don't like asking for help but it's much needed here. Anyway, thanks!
