Packaging an icon with my map?

Making a gma but I’m having an issue. I want an icon to appear in the library when people subscribe to my map but gmad returns an error when it tries to process the icon file.

Is there a howto on how to add a library icon out there?

It would help if you could give some more information about your icon file and the exact error you’re getting.

For my map, I placed a 512x512 PNG (with the same name as the BSP) in the [del]/maps/thumbs[/del] /maps/thumb directory of the add-on folder. I assume the process is still the same.

Just did as you said and I get the error “Not Allowed By Whitelist.”

I believe the folder should be named ‘thumb’, not ‘thumbs’. I see I made the same mistake in my original post, my bad.

Success! Thank you.
