Wow... that looks eerily familiar to this...

Anyway... If you don't need to change it or lose it... just use a persistent
scope for it. Then you can pass it around to whatever you want.
function init_image()
{
application.imgObj = CreateObject("java","java.awt.image.BufferedImage");
application.imgRdr = CreateObject("java","javax.imageio.ImageIO");
}
function set_size(image_name){
f =
CreateObject("java","java.net.URL").init('http://www.sph.umd.edu/images/care
erexpo.jpg');
imgObj = application.imgRdr.read(f);
imgObj.imageWidth = imgObj.getWidth();
imgObj.imageHeight = imgObj.getHeight();
return imgObj;
}

<!--- function to get the properties of the image file --->

</cfscript>
<cfset tmp = get_imageinfo("MYPATH\MYFILENAME") /> <!--- this is
the image file to get --->
<cfset width=#get_imginfo.ImgWidth#> <!--- this is
the resulting image width --->
<cfset height=#get_imginfo.ImgHeight#> <!--- this is
the resulting image height --->
<!--- now define what to test width and height against and what to
do --->
<cfif width gt MYMAXWIDTH or height gt MYMAXHEIGHT>
File To Large
<cfelse>
File OK
</cfif>
