..unless I, during the selection of the picture, change my mind and hit the escape key. It closes the folder where the pictures are stored and takes me back to Excel where I am notified of a "file not found" error that stops everything. How do I code in such a way so as to prevent the error if someone changes their mind about choosing a picture during the process?
