@Newbie Brogo:
Almost EVERY webhost allows direct linking to images...
There is ussually two problems that you can come against when trying to get an image to work on the internet...
1) You need to save the image in a compatible format for the internet, otherwise, browsers can't read it properly (well, it's usually the forum itself that can't read it properly), therefore it isn't shown. If you have Photoshop, go to File >> Save For Web and then save it in the format you want (you may notice a loss in quality, just play with the paramaters till it looks good)
2) Try to take out any spaces you have in your link, and replace them with %20 ("%20" is the ascii equivelant to a space)
After you've done that, youre image will work.
I had a bit of trouble getting mine to work at first, but after i did both of those, it worked fine
Hope I Helped...
