Flickr does allow hot linking. You need to use the pic's url instead of the album's. This does not work.

Posting pictures from multiply??
Multiply does not provide hot-linking for the forum, i guess. Tried everything i can with my own pictures to no avail.
Different hosting sites gives you different html codes, some of which does not allow hot-linking. A few simple rules apply
1. it should ends with a picture format, such as .jpg.
2. a secondary link with a lot of .... in between, may have been altered and only works for that forum or that page. It may not appear normal, if you simply cut and paste this link (which is not complete and original) onto another forum.
3. if trial and error does not work, google and look for another host.
