Do you have Kodak easyshare software. If so I can tell you an easy way to post.
1)goto the pic in easyshare, open it and click edit.
2) click save as, give it a name, then at the bottom resize it to "Best for the web", save it to a folder of your choice
3) Goto Myfishpix.com, upload the photo from your folder
4) open pic in myfishpix, right click and click "copy"
5) go to the thread you want to put the pic in, right click, hit "paste"
6) pic should be there
IF when you try to upload to Myfishpix, it says "file too large", go back to Easyshare and resave the pic ensuring that you picked "best for web" from the resize drop down menu
