RPB's sounds easier than the one I use so I'd try that first.
If for some reason it doesn't work for you, you can try:
http://share.ovi.com/
Once you open your picture on the ovi.com site you need to:
1.) right click on the image
2.) go to properties
3.) copy the url. (it will be long and end in .jpg)
4.) In the Hobie forum- click the IMG button below the subject field
5.) paste your saved url link
6.) click IMG again.
7.) Preview it before submitting and it should be there.
(see what I mean about RPB's being easier
)
