hi ryzek
the function wena mentioned is: 'file' → 'collect for output' (in german: 'datei'→ 'für ausgabe sammeln'). it puts all the stuff you need for the project in a folder (fonts, pictures, vectorgraphics, your .sla file...)
if you don't have such a collection, it's really bad practice to move the pictures of an active project!
the 'path tools' ('pfadwerkzeuge') have nothing to do with document paths – this is a set of tools to work with path objects.
