I want to add file-depending pictures to my Excel sheet. I think the best way to describe what I mean is by giving an example . I want to add a picture of 'the animal of the day' in an excel sheet. The name of the file is animal.jpg. But today it might be a dog, tomorrow a cat and the day after a horse. I don't want to change my excel sheet the only thing I want to do is save the new picture as 'animal.jpg' and the excel sheet shoud display the new picture. Is this possible? And if so, how can I make this happen? Thanks for any help!
