This works most definitely (because I use it in an animation)

#declare PaintingName =
concat("art/MBclear/DK44",str(frame_number-4300,-5,0),".png");
// art/MBclear being the folder where the images are
// DK44 is the base name with the str() bit giving DK4400001.png through
// DK4410000.png

#declare ClearPainting1 =
union {
        object {PngPainting (PaintingName, 400, 225, 1 , 0, 12.5, no, < 0,0,0>)}
        object { ScrewSet }
        }

// PngPainting is a macro that scales, rotates and frames the image

// And here I place it in the scene
object { ClearPainting1 translate <  1000, 412.5, 20> }


See, no need for 1000's of lines bundled in Excel. Since I have a total of
18 of these moving paintings over a total animation of 10.000 frames that
would give me 180.000 lines of case statements. No, thank you. I like the
above a lot more

Hope this helps
