This is surely possible if you do it in a userform with a self-constructed "drop down list". This would consist of some image controls and a scroll control that give the impression of a drop down. This involves macros, so the users must be able to have macro enabled.
there has to also be some text or number associated with each picture.
If you want help with this, I will need a lot more information, so I can construct a workbook with a similar layout to yours.
