I mainly use Liftoff and it looks like it should work, I put the code in, but I don't have luck with it. I was excited to try Boost again, but that has a very bare bones post screen, so I don't even try.
I sometimes just use a collage maker to put them into one image, but then they're small. In trying to build up a picture oriented community (!superbowl@lemmy.world) it stinks to not have more options to post media.
