What I'm doing.
After you're done taking photos.
Go to Gallery, Photos --Library
Click on the first photo--view it.
Press the triangle. A small 'edit' window will appear
Scroll down to 'Export File(s)
Choose Yes
Use R1 and L1 to move to the next or previous photo(s)
The small 'edit window should still appear
Now your photo(s) are located in the PS3 XMB photo section.
The PS 3 will create a Gran Turismo 6 folder.
Now quit the game.
Find a simple 1G USB flash drive.
Go to your PHOTOS.
Scroll to Gran Turismo 6 folder.
Open the folder, but
don't click to view it.
Press triangle
You'll see 'View' and directly below it 'Copy'
When you click Copy the PS3 will choose your Flash drive.
Now remove the flash drive and you're done.
Now everybody try it.
Now for replays.
Do the same thing.
When you go to your Xross Media Bar. The file will be located in the Saved Data Utility/(PS3). Which is located under the Game Icon.
I believe it is possible once you transfer the replay file(s) and photos to a PC you can burn the data to a disc. Send it to someone and they can transfer the files to their PS3.
The file will be labeled 'Gran Turismo 6 Relay with the details and size of file below it.
