      The problem is, that I moved just the image without the frame




Images live in rectangles. To move your image with the rectangle, use this: 

      myImage.parent.move([10,10])





      What kind of object have I created by myImage=app.activeWindow.activePage.place(myFile,[100,50])




An object of type Image. 

      Is there a function that would tell you the name of the object you are
      using?




Straight after placing the image, do alert( myImage.constructor.name ) 

      What magic line is it missing in order to move objects with frames




See above. 

      fit is not a function




This too is solved by addresseing the image's parent: myImage.parent.fit( etc. 

      move 'to' or 'by'




To move 'by' instead of 'to', leave the first position undefined: 

      myImage.move( undefined, [10,0] )
