I can't seem to post any GIF files in my posts, wether in the signature or in the post itself. I have a little collection of smilies that I use once in a while that I can't anymore.
Yes, alot of people agreed that the images were putting people a little off-track from the main point of the post, and also other reasons behind the text.
You should also notice that:
*I have limited to three pictures per post in vB options.
*The IMG will not be displayed if the path to the image contains dynamic characters such as ? and &. This can prevent malicious use of the tag.
