Signature bombing?

New DDoS idea... You head to a well known forum that allows you to make your own html signatures, add in your signature a (preferrably big) image hosted on the target's server, make the image size 1x1, and it will still load the whole picture without it taking up any space in your signature. Put it in your signature 1-100 times, and then just start posting in popular topics. Damn...

Everytime someone visits the page (hopefully lots of people) they will have to load a chunk of bandwidth from the target's server. Depending on how popular the forum is, you could cause a huge amount of traffic, eat up their bandwidth, and possibly cause lengths of DoS. (pick a juicy post topic!!)

Heh... maybe it's a bad idea to share this...
