Perhaps post in the testing section? only you and admins can see things you post there, it will be in your attachments though, every image you upload will be, but nobody can see your actual attachment list, staff might be able too though I'm pretty sure.

@Snow Oh, I didn't know that existed.  Might check it out later! Thanks!

Have you just been uploading to threads or something?
If you have discord there is also another lazy and somewhat quicker and easier way of uploading images as well but you need to send it to at least 1 person.
