Ok let me show you what i mean click on user cp then click on edit signature now on the bottom of that page it says signature permissions their are 2 columns the lefthand side on the bottom it says "Allow HTML No" i need to change that to a yes. then the bottom 2 on the right hand column say. "Can Upload Images for Signature No
Can Upload Animated GIF for Signature No" i need to change these also to yes
I do not think we can edit those permissions. They are the same for me. I am assuming they are the same for everyone else. That is why I have my own website where I upload the pix I want to use for my signature, and then I use the html coding function to link to those images. Since my time as a web page builder was very long ago, I just click the 'insert image' icon I told you about which is the little yellow square with 2 hills in it, and input the URL to the files I have uploaded to my own website images directory, and the interface does the rest.
I would think that most of the sigs you see with gifs, animated or otherwise, are images that are linked to and located elsewhere.
