I have been going over this for the past couple days trying to figure this out. Aparently ther is something in the code in the foru that limits pictures to a width of 300 pixels when using the bbcode img tags. If you imbed the picture with the tinymce picture button it will make it full size. I have been through the .css files that write the code to create the forums as we see them to no avail. I have a couple more things up my sleve that I will try but if they don't work we may be stuck with 300 pixel wide signatures.
