To print images from the internet on your report, insert a picture object on your report at the proper location (use a default image file to start with). Then right-click on the graphic and select Format Graphic. On the Picture tab there is a Formula button for the Graphic Location property. CLick on it to insert a formula that returns the URL. Something like this maybe:
if {table.field}="red" then
"http://www.website.com/red.jpg"
else if {table.field}="yellow" then
"http://www.website.com/yellow.jpg"
else
"http://www.website.com/green.jpg";I discuss this technique in the chapter Advanced Formatting Techniques in my book
Crystal Reports Encyclopedia.
