yah. I know about doing that. Its a good temp solution.
I guess I was more referring to the have a install box in the user cp (like that imageshack hack) that lets ppl upload directly from their user cp (edit signature area), and that would automatically upload to the signature section in the gallery.
then...for those that DONT know what its all about and are just looking at adding their signature edit page.....have something that clues them into the whole process (or faciliates and/or promotes doing so).
just a little box "upload your signature image here" in the user cp (that uploads to the gallery designated category) is all I really meant.
