i am requesting the ability to insert an image URL into my signature line.
One particularly selfish member of the forum included a dynamic image in his signature (like you want to do) but failed to properly test his code. The buggy code sent corrupt massive images. Bear in mind that, because the image was dynamic, EVERY SINGLE POST OF HIS CURRENTLY IN VIEW required fetching the image. His mistake left the forum inaccessible. Adding insult to injury the miscreant refused to remove the signature; insisting he could not possible be the cause. I wasted about 30 hours of my life dealing with his mistake and his bullshit attitude.
I will fight tooth and nail to block signature images on this forum.
In any case, the moderators no longer have the ability to enable signature images so you would have to take your request "upstairs".
Just so you know, this...
$json = file_get_contents("http://tjfserver.ddns.net:8000/status-json.xsl");
...is a serious problem. If your server is down we will all wait for file_get_contents to timeout. For each of your posts that is visible.
