I'm not sure what the problem is, as it seems to happen sporatically, but you can always just post it with the attachment feature if worse comes to worse - that seems to work pretty reliably now.
The correct synatx for posting an image is as follows:
<img src="http://www.domainname.com/photoname.jpg" width="400" height="200">
as for your question wayne, there aren't any dues to be a moped army member right now - the requirement is just keeping active and involed with the moped army. the hosting fees are getting to be quite a bit of a cost though. I hope to defer the costs in the future a bit by selling some items like stickers and t-shrits through the website.
one thing i will never do is host banner ads or any other sort of non-moped related ad on the site -- i'll find a way to keep digging up the money before i give in to that.
