Help. epicly. sig won't load to mpgh

I have had a signature for a while now. Come to find out yesterday when i logged in my sig pic was missing!! Tried ********* another and made a whole new 1 when i click upload it does nothing. any1 know why??

Upload it on a site like Wimg.co.uk, imageshack.us, or photobucke*****m.

Then go to user CP, then on the left go on 'Edit Signature'
Then in the box put [img]LINK OF THE SIG[/img]

thanks worked. maybe i can get my old sig back
