tell me how to put KSanpshot in the panel.
If the widgets are locked, unlock them. (Right-click empty space on desktop and choose "Unlock Widgets").
Open the K-menu and look for "Screen Capture Program" under "Graphics".
Right-click the entry and pick "Add to Panel". Or you can
drag it to an empty spot on the panel.
Click the panel cashew and drag the icon to wherever you want it on the panel.
(Personally I prefer to start KSnapshot by tapping <PrtScrn>....)
