Thanks! Works perfectly.
The developer I work with points out that sometimes you might want the image
cached unless it has been updated, and the solution to that is saving the
modification date of the image in the DB, and outputting that to the image url
as an integer. To express a date in integer form, we typically use the number
of seconds that have passed between a fixed date in the past and the date in
question. So, <img src="image.gif?#datediff('s', application.startDate,
getImageQuery.lastModificationDate)# />.
