Mr. TyeJae,

If only you could select a picture displayed on your worksheet ; then,
look at the NameBox (located to the extreme left hand side of the
Formula Bar): it gives the name of the picture you have just selected.
Edit the name of the picture according to your preference.

Study the relevant thing on the web-site of McGimpsey and Associates
and there shows a very decent example of putting pictures (c/w VBA
Coding) on Excel WorkSheet.

Regards.
