The image doesn't seem to be there; so I am unable to help with that part just yet.
However, the automatic image naming has problems because of the way UBB uses message icons. The icons themselves have to be named icon1.gif, icon2.gif ... iconxx.gif where xx is the last number in your list.
The version number is the name of the zip file. Thus far, there have been three versions. 1_0, 1_1, and now 1_2.
I am amazed that you took the time to rename 800+ smilies to reflect the proper number sequencing of message icons. I'm impressed.

I'd be interested in seeing the screen shot.
