What's your deal with PNG images? Why can't you take them?

My 'deal' would be that if you send me art that is a PNG image, I can NOT copy it and properly save it to my computer and load it onto the club's gallery.

Why?

It's the design of the file is all. I support other files, except PNG. If you send me a link with a picture in PNG format... I will NOT be happy with you about it.

Sorry if it seems harsh, but its a pain to contact you, ask you to chnage it, have you chage it, re-note me and ect.

So please, refrain from using PNG images.
