Ok guys, I am just getting ready to do this myself for the 6.2.1.1 upgraded files, so I will see if it's a bug or what may be happening. How did you install it? via multihack or text instructions??
Did you upload the graphics files to your non-cgi folder?
If you did go in to your styles template and see if the images are there. If you have multiple style templates you must do this for all of them. If they are there when you look at your styles templates, then rehack ubb_lib.cgi. If they are not check cp_vars_style_core.pl and cg_styles.cgi to ensure you hacked them right.
what version of ubb you running and what is the link to your boards with the problem so I can look at it?

Well I assume you two must have figured it out since there is no response to my questions?
