Since the lycos image hosts were setup, many freehosts such as imageshack and photobucket have since popped up and offer much more stable hosting.
Due to bandwidth issues, several of the mirrors hhahscreens1, 2, 3,etc have been shut down, and there appears to be communication problems with members.lycos.co.uk with some uk isps (as far as i can gather, wargand says it works for him but i can't get on them).
For the sake of stablity and longevity, it would be wise to backup your images and move them to a photobucket, imageshack or similar site.
I can't get on to any lycos site via ftp for quite a while now so unfortunately i'm unable to mass backup any of the surviving lycos image dumps. I have previously tried from work, will try again through the alternative proxy they have to see if i can back them up.
PM me any links/guides that mention the location of the image dumps so i can replace them with a more modern alternative
