If you've blocked any domains, try unblocking them. Domain blocking is buggy and will hide random stuff from you.
I've got the photo post bug too, but it only seems to affect me on @anime_irl, while @animemes seems to still work fine.
Also, you posted this multiple times, may want to delete the other ones. Whenever you make a post, check the "newest" sort order to make sure it went through, and then upvote your own post to make sure it's visible for everyone on the default "hot" sort order.
