Find: objImage = imagetools.getImage("#file.serverdirectory##file.Serverfile#"); Replace with; objImage = imagetools.getImage("#cffile.serverdirectory#\#cffile.Serverfile#"); It was returning -1 because the author forgot to add a backwards slash. And, file should be cffile.

After uploading your image, use the following code to calculate it's size.
<cfscript>
imageObj = createObject("java", "java.awt.Toolkit");
imagetools = imageObj.getDefaultToolkit();
objImage = imagetools.getImage("#file.serverdirectory##file.Serverfile#");
width = objImage.getWidth();
height = objImage.getHeight();
</cfscript>
Then use the values how you wish, to store in a database, deny an upload according to sizes etc. The following just outputs the values for info.
<cfoutput>
width: #width#<br>
height: #height#
</cfoutput>

I have tried with the full directory path, still it returns -1
-
If you replace #file.serverdirectory# with the full directory path, then the code works just fine!
-
You would get -1 if there is nothing to evaluate, i.e the image has not been uploaded or it was a zero byte file or you have specified an invalid path to the image.
-
The script seems to return "-1" for both width and height... ami I missing something?
