The image expression is not "the name of the file" but an Expression. If you set the expression to foo.gif, this is static, but ...

 

$V{mygif}

$P{mygif}

$F{mygif}

"c:\images\"+$P{ProductId}+".jpg"

...

 

are all valid image expressions.

Plese note that iReport can't evaluate an expression to show the right image in designer (you'll see a special image instead), but you'll see it a run time.

Might I add you could define a variable as an image URL location that you can use as a parameter to the URL class. in Ireports you can then use the variable to input the image expression as

new URL($F{imgvar}.toString()) remember to set the Exp. class to java.net.URL
