What am I doing wrong?

That path you see at the top of the backglass screen tells you what is needed. The backglass image that you wish to display must be named the same as the pxp file in the Pinball FX3 directory and also be located in that directory. You will need to copy your PinballX image (.jpg, .pdn...) to the Pinball FX3 game directory. The text at the top of the screen lists the acceptable graphics types.

Thank you Kencaine
I am pretty sure I have them named correctly and installed in the correct folder....backglass listed directly above game file,with extension...named the same as game

I have never been able to get back glass image to work in cabinet mode,however when I load FX3 games into PinballX front end,the back glass IS displayed correctly....UNTIL the game launches then Just the file path shows at the top of monitor as it does in game on PinballFX3.
All other games in PinballX work perfect,back glass display is correct
Thanks
