(I yam a techtard...)
Yahoo blocks them? what if you use something other than Yahoo? (I yam a techtard...)
I have three major web sites in Yahoo - with some sub web sites included. (See my FR bio page) One major site is my Tolkien Dictionary, a major international web resource. I am just too old to move all of that.
I can usually find a graphic that I can use. Hint: if you find a graphic on a search engine, right click on that graphic and choose "Open image in separate browser window" or similar and choose that url address. Isolate the actual origin of the graphic; that will usually yield a useable clean link. Occasionally the image is twice removed (Foldspace's images); be patient.
