Hmmm... I don't know. Weird that Huss can see the links but myself and others can't. Nothing has changed with my ftp hosting.
I went to a few of my older FM posts and they all have question marks now unless I posted them with Upload and Sell on. They definitely worked when originally posted. (Some from 10 years ago!)
I went through and looked at the source code for the FM forum pages, and it looks like *most* people use either Upload and Sell, or link from an image sharing site like Flickr, SmugMug or Zenfolio. I bet it's a security thing - blocking external links that are from private servers?
I have a Flickr account. I'll try posting images there and then link here.
