Problems with avatar if conditional

[DataHero]

I took a look at both files and at the right location (which you mentioned). I'm not an expert at PHP but do understand most statements and whatnot. However, I did a search and came across this post.

If what Brad has said is true, where would I have to put the code? That is, the script.

Cheers.

Edit: Well I've added a plugin with the contents of the first code block that Brad posted (see link), and tried global_start. That didn't bring up errors, but it wasn't displayed either. Then I tried the showgroups_complete, showgroups_start and showgroups_usergroup, which gave me two errors (the page didn't stop loading though).
