In Linux, you might want to take a look at a program called gThumb, an image-management application that in several ways nicely complements GIMP. In gThumb, you can cause an image to open in GIMP either by right-clicking on the icon and selecting GIMP from among the list of options, or by dragging the icon into the GIMP toolbox. See the gThumb home page [GTHUMB] for more information. Other similar applications are : GQview [GQVIEW], XnView [XNVIEW].
