image in cell
Inserting images in Excel, it must be a little easier to insert pictures of which we have a weblink for.
i.e. making a list of LinkedIn contacts, where you would like to insert the profile picture (weblink available from LinkedIn page) into a cell that is already sized. The picture should fit INSIDE the cell, NOT over the cell.
Check out Google Docs, they have this exact function. I would really like to see MS do the same, if not better.
Google doc also allows for the insertion via formula:

Somewhat related to this is the ability to paste an image into a cell note. The use case I have in mind is being able to put pictures of receipts in a note for the cell showing the total. Ideally I would be able to put multiple receipts into a note.
