How to load xbox game covers

Hello everyone ixPrankster here

I am in need of some help

I have some game that are missing game covers

and I tried almost everything to figure it out

but I can't

I have linked my RGH with JQE360 and when I go the the site
I click install and all it says your item is in your Q, or something like that

Can anyone help me figure this out

Thanks for any help
