Nostalrius Begins - Quality wow vanilla realm (1.12)

When I update my signature it fails to work if I put IMG tags in and I get a bad gateway. I've tried both a small 12k-ish png and jpg and both did not work. Sig updates just fine without the image tags.

This has been broken for a while now. Signatures won't save if they contain [IMG] tags. I've mentioned it in a few other threads but sadly there's no telling when it'll be fixed.
