ColdFusion 8.0.1 Bug Coldfusion.Image.ImageWriter $ ImageWritingException
Posted July 17, 2008 at 9:34 AM
I just came across a known bug in ColdFusion 8.0.1. Apparently, sometimes the ColdFusion image functions don't play nicely with JPG image files and throw the following error:
An exception occurred while trying to write the image. Ensure that the destination directory exists and that Coldfusion has permission to write to the given path or file. cause : coldfusion.image.ImageWriter$ImageWritingException: An exception occurred while trying to write the image.
Some quick googling found that there was a Hot Fix available for ColdFusion 8.0.1 image functions. I figured I would post it here in case anyone was running into the same problem.
ColdFusion 8.0.1 CFImage / Image Functions Hot Fix
ColdFusion 8.0 And Later Hot Fixes
I installed the above ColdFusion 8.0.1 Image hot fix, restarted my ColdFusion service, and the image that was breaking my application started working again.

Hey Ben, I've been working with the jpg issues for a while. I've noticed that some jpg's don't play nice even after the hotfixes are applied.
It may be a hack, but I got fed up and had to do something....I'm converting the jpg's to gif's (usng CFIMAGE action="convert") after they're uploaded and then doing the CFIMAGE manipulation (resizing etc) on them. Its an extra step, but it's working like a charm for my site.
I hope this helps!
@Dan,
Interesting hack. Unfortunately, converting a large JPG to a GIF will increase the file size greatly (in theory)? But, good to have at least on solution till they iron out the kinks.
Thanks for the Tip, this problem was driving me crazy, 1 jpg works fine, then next one does not!
Your site rocks!
I had the same problem, and the hot-fixes didn't seem to help. Not quite sure where the client was getting their jpgs from :)
As a fix, I found that saving the image to disk and then reloading it worked. The extra step seemed to convert the jpg to a format that didn't have the problems.
It's not perfect, as it slows things down and probably reduces image quality. It required the least effort though, and doesn't have the issues associated with converting the image format to gif.
Thanks so much!!!
@Gareth, can you explain further how you got this to work. the hotfix is not working for me either and converting to .gif's is too much load and file size. what do you mean by saving the image to disk and then reloading it. can you provide sample code?
It's while ago, but I think I just used cfimage to save the file without modification.
I then reload the new image and do whatever manipulation that's needed.
It doesn't fix all images, but reduced a lot of the problems
Thanks Ben, that did the trick for me, I applied the patch and the jpgs are now working.
Cheers, that was a lifesaver, spent a week or two on and off on this problem
I'd still be starting at a page of code if it wasn't for this post: I had an issue with three file uploads in one form that stopped working after we upgraded to 8, thanks!
@Garry,
Glad to help :)
I commented earlier about converting .jpg's to .gif as a workaround. I've since learned that my .jpg problems stemmed from trying to constrain both the height and width of the .jpg using CFIMAGE action="resize". Sometimes my users would upload a .jpg (book covers in this case) and the dimensions were such that constraining it too far "out of whack" from the original size would cause the page to break. I've since removed the "width" attribute of the CFIMAGE tag, but I still explicitly set the "height"...the width is constrained automagically (thanks CF)...it works perfectly except for the occasional user that uploads something really funky...like a banner image rather than a book cover...lol :-)
@Dan,
Good tip to know. Thanks.
I found that using the cfimage info to determine what's been uploaded seemed to be best, so I have something like this
<cffile action="UPLOAD" filefield="upload2" destination="#application.path#www\alt_images\" nameconflict="MAKEUNIQUE">
<cfimage action="info" source="#application.path#www\alt_images\#cffile.ServerFile#" structname="info">
<cfif info.width gte info.height>
<cfimage action="resize" source="#application.path#www\alt_images\#cffile.ServerFile#"
destination="#application.path#www\alt_images\thumbs\#cffile.ServerFile#" height="" width="100" overwrite="yes">
<cfelse>
<cfimage action="resize" source="#application.path#www\alt_images\#cffile.ServerFile#"
destination="#application.path#www\alt_images\thumbs\#cffile.ServerFile#" height="100" width="" overwrite="yes">
</cfif>
@Garry ....awesome idea! thanks for the tip!
The cumulative hot fix 2 for CF 8.01 includes this hotfix and a pile of other fixes.

You will also want the hotfix that fixes a vulnerability in FCKEditor (it is not included in the patch above).

Another interesting twist on this issue for the benefit of anyone else who might have trouble. We were using CF8 to write images across the network and had to alter the run-as user for the CF instance in order for the image writing to work.
However, when re-starting the instance via JRun Admin, those permissions were not set - resulting in the aforementioned exception. Re-starting the Windows service that CF was running under fixed the issue.
@Scott,
Thanks for the links. I need to check to see where my server is on these updates.
@Jeff,
Very interesting situation you got going on there.
