Please help me.
Go to the main gallery screen.
Just above the search box on the right hand side of the screen, you'll see a link for "Upload Photos"... click that.
Fill out the details on the next page, these should be pretty straight forward. Just remember, choosing which gallery you upload to impacts who can see your photos.
When that's done, just click the "Upload/Submit" button and you're done.
Go to main gallery.
There should be a uploading thing in the corner of the page, right next to profile, search, and home.
Click on it and that were you can upload the pic you want from the computer to here.
