Hi....once again I'm stuck and need some of your expert help!!!

I have several pictures on one worksheet labelled pict_1 to pict_x, and would like these pictures to be the source of a drop down in a range of cells in another sheet .. e.g. a1-a10.
Once a picture is selected then the picture is displayed in that particular cell, and each cell in the range can be any of the pictures or blank.

I have searched high and low but can't get exactly what I'm after, so hope you can help!

Thanks for looking.
