Hi & welcome HRLMT,
Sounds an interesting background. You a game artist, programmer or story writer kind of thing in the game process.
Have no idea why you cant save an image. You should be able to click on an attachment thumbnail, get the black bordered 'light box' of it. Click again to get the browser to show the image on its own with usual white background and then right click save image as...
By that point if it does not work id look at your pen drive.
Ravells plays Traveller. Been a few posts about it in the past and a few maps for it here.
