I just tried to install this on a custom style.
If there is a description, then it wraps around the description.
Please take a look at
www.bloodbanktalk.com, it's in the top forum Site Support. For now I just put in a test link, not an image.
Also, the first part of the instructions say to edit forumhome_forumbit_level1_nopost, but I don't have the Find statement there, I searched for it and found it in forumhome_forumbit_level1_post.
I also have the Element style installed, I just added it to that too, and I still get the wrapping.
I really hope this can be adjusted.
