Hey dude, on all of your requests you have been posting the wrong code, pretty much every sig you have made so far is unused because of this. When you upload to photobucket, copy the image code and paste it so it shows the image, but them click on the html code button and put the image code inbetween the tags. This will show the code in full so that the person may just copy and paste it into their sig space and move on.
HERE is an example of a good thread post.
