How do I submit to a certain sub on Imgur?

I can’t figure this out for the life of me. I can’t find instruction on Gogle or Imgur help. If I want to submit an album to r/technology, what do I do? I’ve spent 20 minutes on this, and they’ve very cleverly hidden the instructions.

When you click submit it gives you a box to fill in what subreddit you want to submit to

If it were that easy, I wouldn’t be asking. No it doesn’t. You can use a tag, but there’s no information as to what that will do. Is that what you mean? The idea of a sub is NOT mentioned when publishing an album.

sorry I’m dumb I was thinking of reddit not imgur
I’ve never done it on imgur

The subsections (Imgur: The magic of the Internet, etc.) are tied directly to reddit. In order to share an image on the Imgur subsection, you have to first post it on the subreddit with the corresponding name, at which point it will be automatically added on Imgur if it reaches a certain popularity.

Since there are pictures in Imgur: The magic of the Internet, I don’t understand what’s going on, as I was denied adding my picture album to the subreddit.

That’s a tag, not a sub. Cardinal posted the correct way.
