dynamic image element display

[beekerc69]

Can you use an expression to evaluate data and print a particular image file?

currently, i have 3 images Red, Yellow and Green (standard grapic stoplights)

i stack all 3 at the same X & Y position.

for the red one, i set the Print When Expression  to $F{STATUS} == 3

for the yellow one, i set the Print When Expression  to $F{STATUS} == 2

for the green one, i set the Print When Expression  to $F{STATUS} == 1

but this means placing 3 (or in some status displays, as many as 8) icons.

I'm hoping there's a way to build an Expression to evaluate one or more dataset fields and have the image resource to be displayed to be determined by the Expression.

Can this be done?

Yes. Try naming image file to be the result of the expression.
