LunchMonitor,
My guess is netfirms.com and freewebs.com will not let you link a picture. It is in their Webserver software to block it. Without going to either of the sites, I am going to guess they are free and have ads built into every page anyone creates on their servers. If they want to make money on the ads they have on their site people have to open pages that are actually hosted on their server, so they block all remote access to pix, etc.
Take Care,
Richard
