Hi. Have you yet tried to upload one?
If not.
Go to your Profile page.
Click Upload Image
A page appears saying 'browse'
Go to where your jpgs are stored.....Windows? Picasa? Documents?
Click "Select" at the one you choose
Click Submit
It will start uploading to your profile page here.
Then you title it,add Description,all other info required at that upload page, then click SUBMIT !!!!!!!!!!!!!! (often forgotten)
Repeat for each image.
Wait a day for it to show up in FAA search via your tags......
