This guide lets you mass delete, privatize, or publicize all of your artwork or screenshots at once without having to manually check each one. Steam has a feature for this but it has a selection limit.

Go to your artwork or screenshot hub and select "Image Wall".



This is optional, but you can filter by a game if you want.



Click the manage screenshot or artwork button.



Scroll down to the end of your artwork or screenshot gallery. If you have a lot of images to scroll through, use the auto scrolling script in the codes section and wait until it's finished after pasting the code.



Now choose the code you want from the codes section below and send it through the console.



It will ask you if you're sure after the code is sent.



If you want to go back and deselect a few images, click cancel, uncheck the images you don't want to change, and then resend the same code but without the SelectAllScreenshots(); at the start.
