Should I be able to upload a picture into a post in this forum?

There's a camera icon here, and it takes me to a dialogue where I can choose a *.png file from my computer, but then it doesn't upload because I get an error "All content must abide by our acceptable use policy." I had a similar error when trying to upload my book cover, but found out that it was spurious and that "Save Draft" worked just fine. Here, though, there's no Save... Hmmm.... I'm going to try again and click Submit. Maybe my picture will be there. It illustrated a problem searching for a group. Here goes. Well, it's there with a white X in a red circle after I clicked Add. Now I'm going to click Submit.
