A picture function is available in Computed Items so that you can associate an image with a computed column. In the Results and Table section, the picture is shown as descriptive text instead of the image in each cell in the format <<Picture:unique id>>. The unique id is tooltip text if any has been specified, otherwise the unique id is the Resource name. In the Reports section, the computed item containing the picture can be shown graphically, For example you could use an “if else” statement to show an image if a certain set of conditions are met, and another criteria if the condition is not met:
:if (Amount_Sales >= 10000) {Picture ("C:\\graphics\\smile.gif" )} else{Picture("C:\\graphics\\crying.gif" )}
