How to Insert a Picture Into a spreadsheet Cell in Excel.
While Microsoft Excel is used as a way to store big Excel data base, it is also a easy way to store some pictures along with that Excel data.
You might have a big and long spreadsheet of products catalog and including an extra column of data with an image of the product into spreadsheet cells.
You can manually resize the cell so that the picture is contained within it.
You can do this by clicking the right border of the column letter at the top of the spreadsheet, then dragging it so that the cell is wide enough for the image. You can then repeat this some times.
