I've just tried a couple of comments for this test album I made using the code Imgur gave, but it never worked. Most times, the comment was blank (even after refreshing), but one time it just hyperlinked to the album URL with "Testing" (the album title).
I'm going to paste the code below these few sentences. It may or may not work here, but it doesn't appear to work in comments either way. Here's a Pastebin link to the code text. Does anyone know why it doesn't work in comments and forum posts (if it doesn't show up now) or how I can embed albums another way?
