I have made a series of dividers for my personal storage solution, but for the Voice of Isengard expansion I have been unable to find the icons anywhere in order to do this.

Does FFG make these available for players to make their own dividers considering they don't have any in the Support section of their site?

I make my own too, and often I want to make them before there are any images available online... so I scan my own. Here's my icon set for VoI. Keep in mind I don't use photoshop and I crop out each image from the instruction booklet by hand using the eraser tool in mspaint
