Give me a woman who loves beer and I will conquer the world - Kaiser Wilhelm
"Wasser ist für waschen, nicht trinkens. Bier ist für trinkens"
translation: Water is for washing not drinking, beer is for drinking. Poppa Boxhiemer
Gimp is pixel based and Inkscape is vector graphics. It's really two different worlds.
In Gimp you would retouch your photo, image or whatever, then import to Inkscape to add text and line art.
