Forum Statusicons: I want to use my animated gifs intstead of png
 

Like the title says, on the old vb 3.8 site i had, my statusicons were animated gifs. All i did to use them was overwrite the default gif and use its name. Now, all the new statusicons are png format, so there cannot be animation to them. I cannot simply overwrite them and use the same name.

In some template somewhere, there has to be a place that lists each statusicon so that i can change the filename from, say:
forum_new-48.png to forum_new-48.gif

Can someone place tell me which template(s) i need to edit?
Thanks
