That's a pretty plain explanation...
Go to www.fototime.com and create an account. You'll have to download their software to your computer, but it's a small program. You can get a free one for 45 days. From there you can "upload" pictures from your computer to that site. They'll be stored there for you as long as you like, or 45 days whichever comes first...
From the fototime website after you've uploaded the photos you can assign a "url" to them from your "share pictures" button on the left in the tools area.
Follow the easy steps and a "url" will be created, just copy the address and paste it into your posting at "www.contour.org"
For example,
I'm at www.contour.org filling out a pic posting. I type all I want to say "blah blah blah"
Then I scroll down the screen to "instant UBB code" right below where I was typing.
I hit the "image" button, and a window will pop up. Paste that url address right there. hit okay and there you go.
You'll have to do this for each photo, one at a time, so it's best to assign url's to all the pics, paste their addresses onto notepad and then paste them one at a time contour website. Much easier then going back and forth between sites.
Good luck.
p.s.
to test your pic there's a "preview post" button right below where you'll type in the contour website. Push that once you think you're ready and your post will appear. If you did the pic right, it'll be there
Have fun!!
