signature pics

a lot of my members are having problems with their signature pics. They said they show up on the preview but dont show up when posting. I have also tried to install the images for some people but nothing shows up. I got my own to work fine so I cant understand it ????

Oh,do you mean that the signature don't show up at forum?I know the matter mate,I think.Hear what to tell them to do:
Go to your profile.Select ''options''.You will see somewhere to write,almost this (I don't know exactly because I've a greek forum): ''Do my signature always appear?''There will be for sure the word signature.Tell them to turn on this option,and accept by press a button down ahead at their screen.All right!If you have any question,ask me.

Thanks bro for nice explain

Hi thanks for your help I have said this but sometimes they still dont show up..... Im sure I will figure it out... Thank you
