Embed image in excel
 

Hi,

I am helping a charity create a spread sheet and they would ike to have
adverts on their excel sheets that one of their users can change easily. I
have used the import data from a text file for the text of the advert but how
can I do this if they want to add or change a picture, I would like this to
be automated so that when they change the image on a server it will update
the picture on the spreadsheet the next time it is opened, or whatever just
like the text does.

Is this possible and if so how do I do it....

Any help would be great. Thanks in advance.
