Thanks all for helping out the noobs like me. Most things in LB are blissfully intuitive (unlike HS, where I come from), but adding icons for platform categories has me stumped. Specifically, where the icons are stored on the screenshot below for "platform category". As you can see, I'm missing ones for Genre and Pinball (and its subfolders).
I'd have thought that I could put them in Launchbox/Images/Platform Categories (which I did) and then right click the platform category to which I want to add the image, like I've shown in the screenshot below. But that shows I already have a bunch of icons in there, including ones for the Clear Logo type, but they don't show up as shown in the first screen shot. I suspect maybe this has something to do with the Theme? But I'm using the default theme, so I'm just confused how to add the Platform Category icons. Help!
