Linux supports an image-management application named gThumb. Besides being an excellent image browser, you can right click an image, choose Open with, then select GIMP from the list of options. You can also drag an image from gThumb onto the GIMP toolbox. See the gThumb home page [GTHUMB] for more information. Other similar applications are : GQview [GQVIEW], and XnView [XNVIEW].
