1. Go to photobucket.com and sign up.
2. Once signed up, log into to it. There will be a menu allowing you to upload picture files.
3. Once uploaded, they will come with the (basic) tag that, in your profile (or an FR posting) allows them to be displayed.
Here is an example of my photobucket page (before I uploaded the image you see):
The rabbit picture tag looks like:
<a href="http://photobucket.com" target="_blank"><img src="http://i28.photobucket.com/albums/c236/sionnsar/bunny.jpg" border="0" alt="Image hosting by Photobucket"></a>
Put that in your posting or profile page, and see the picture.
Two very helpful, very pretty explanations... Nicely done!
