It is a 8bpp PNG image. To use it as your toolbar icons, you’ll need an image editor and a resource editor. First open the image in your image editor, create a new layer below it, and fill the layer with the background color of your toolbar, then save the image in BMP format. After that, open gvim.exe in a resource editor (for example ResHacker), choose BITMAP in the tree, then choose 101, right click on it and then choose replace resource. Choose the previously saved tools.bmp, then choose File -> Save and you are done :D
