I'm pretty sure that it's required for it to work to begin with, unless it calls some functions tied to IMG loading.
Tested ImVehFt and IMFX.
IMFX seems to be compatible with UG, but ImVehFt is incompatible and will crash the game. I guess fastman's patches didnt execute. I'll try to make it compatible.
It's compatible now.

I'm pretty sure that it's incompatible. If so, i'll make it compatible.
