If it is a dynamic (bound to a field) image element, set the LE to the name of the image file, or if you have no default image path set - set it to the path to the image file:

MyImageLE = "MyImageDir\MyImage.jpg"
 

You may have to call ForceRedraw to see the change immediately.

If it is a static image and you are using 1.0.5, you can follow the instructions above, but always use the path. If it is static and you are not using 1.0.5, you can't change the image from the image set in SDesigner - its static.

I'm saying that the value of a dynamic image element (image field) is the path or filename of the image. If, for example, you view your form in "table view" (Shift-F6) and look at the image field, you will see that it has the filename (possibly the whole path) of your image as its value. Just like a numeric LE might have the value of 67.0, an image has its filename.

To change the image that is appearing, simply assign its value much as you would a any other LE. In the case of a number, you would use the assignment operator "=" - for instance:

MyNumericLE = 67.0

You use the same syntax to set a dynamic image, but instead of a number you use the filename of the image as text:

MyImageLE = "ImageFileName.jpg"

When your form sees that an image LE has been changed, it knows to look for that image file on the harddrive, read it in, and display it. Sesame then stores the filename of the image in the database files as the value of that LE/field.

I am assuming your line items are in a subform. If that is so is your subform a Table view subform by any chance?

If you double click on your image element does it bring up the image browser?
