Thanks for the reply. It works when you're just posting in a forum, but it doesn't work when you're using the poll feature. Polls always required a special format to embed pictures. The picture url had to be placed within brackets and some extra characters - img scr at the beginning - here's an example :
<img src=https://i.imgur.com/VwCQb3R.jpg>
Typed this way, the picture appeared in the poll. I guess the Poll feature is set up differently from the regular message boards. Anyway, I tried using just the photo url (like you showed above), and it didn't work. I tried every other picture link that Imgur provides (Image Link, Direct Link, Markdown Link, HTML, BBCode, and Linked BBCode), and none of them worked - no picture, just a clickable link. I pm'd the Shopping Channels moderator, CuriousParker, who also tried several different ways to get pictures to show up, and none of them worked, which is why CP suggested I post the problem to the Bugs forum. Maybe the recent software update changed how you have to format picture urls in the Poll feature?
