I used Mr Excel's tip on inserting an image into an Excel sheet using a Comment. It requires using the Data Validation to change the names and bring up a new picture. First question can this be done without having to use Data Validation? Secondly, I am using Excel 2010 when I send the spreadsheet to someone using Excel 2007 the Data Validation is no longer there and I cannot create it on his spreadsheet on his computer, why?
