I want to change the icons used for different folders on the Raspbian desktop. Does anyone know if this is possible on the Raspbian LXDE desktop?
You can change the appearance of the folders (and the rest of the desktop for that matter) by clicking "Theme and Appearance Settings", under preferences, in the menu. Don't see it? That's OK, sometimes it's hidden. You can un-hide it in the menu editor, or simply run the equivalent command in the terminal:
You are interested in changing the folder icons, so head over to "Icon theme", like this:
Each icon theme (on the left) will have a different appearance for the folders.
When I googled this, I was looking for the custom folder icon size to create my own icons for images to display from the menu editor. This may help someone.
This is as depicted if you were to add a new menu item. Adding a new item prompts you for the path of a 128px square icon. The line also represents what you would find in an LXDE menu if you were to ever edit one.
