Sweet, good tip!

Very nice! I'll edit my post to include that.

I don't know if anyone will find it useful, but to download all box art in the highest resolution (assuming Unix-like os, only tested on Linux), go to your account and save the webpage as account.html. Then open a terminal, cd to the directory where you just saved the file and use the following command:

cat account.html | grep -o -E '{4}/[0|1][0-9]/[0-f]{40}_bbC_20\.jpg]https://www.gog.com/upload/images/[0-9]{4}/[0|1][0-9]/[0-f]{40}_bbC_20\.jpg' | sed 's/_bbC_20//g' | xargs wget

(I suggest using another folder than your desktop)

Smart stuff. I do love a clever bit of shell scripting to get the job done. I do a lot of it myself. Thanks for the handy command!

Curious addendum, when I save my shelf as a file, it only saves the first ten rows of the shelf. Even when I view the source it's the same. I'm guessing the rest are built out through scripting and don't appear in the page code.

I'll see if the list view works better.

EDIT: List view is a no-go. It seems to get all the titles, but the image names are unrelated to those of the box art images.

The workaround I used to get the whole shelf is to choose Inspect Element on div.shelf_main, copy the Inner HTML, and paste it into the source file. Then it has the full list.

Well, I'm going to go ahead and mark the post from Snickersnack as the solution. Thanks to everyone who posted all these neat tricks, clearly there is a lot of treasure hidden below the sands on this site. :)
