I've been seeing alot of people posting images from some free providers that don't allow hotlinking and such.

I came across a pretty good free host you might be interested in.

100 MB of Space

You can't use this to hold files such as zips exe's etc, but you can have 100 megs of images which is cool.
you can even zip all your files and it'll unzip them for you on the server.

I don't use this but it might be of interests to some.
