The DevExpress ASP.NET Spreadsheet (ASPxSpreadsheet) allows you to insert pictures into a worksheet.
To insert a picture, select the cell where you wish to place the picture and click on the Picture item within the user interface Ribbon's Insert tab. The pictures to insert may be located on your computer or on the web. You can also move, transform and delete pictures in a worksheet.
This demo shows how personal photos can be programmatically added to each data row containing employee information.
