Coldfusion 8 Error: Invalid image format or slow performance - image-processing

Question

Trying to troubleshoot someone else's not-so-great code. Any ideas would be greatly appreciated. It seems to bomb out at the <cfif> that brings in the image:
<cfif LEN(qryCampers.std_image_filename[iRow + iCol]) GT 0>
If I comment out that if (and only keep the section related to the "no_image.gif" out of the cfif statement) we're good. The document appears.
CF Server 8, SQL Server 2000, Images are relatively small in size (all under 30kb, no more than 300px in width), this code works some of the time and when it does, it takes FOREVER to load the PDF. This particular query (only 12 records) is causing the error.
The Error:
Invalid image format
The error occurred in D:\apps\Websites\Example\app\reports\dsp_camper_cards_preview.cfm: line 51

Answer 1

As far as your invalid image error, we had a similar issue with invalid formats and slow performance. Our solution was to convert the image to a png then back to jpg using cfimage. We did it as the image was uploaded but you could do the same thing in your situation.
<cfimage source="#expandPath('\images\temp')#\#cffile.serverFile#" action="convert" destination="#expandPath('\images\temp')#\#cffile.serverFileName#.png" overwrite="yes">
<cfimage source="#expandPath('\images\temp')#\#cffile.serverFileName#.png" action="convert" destination="#expandPath('\images\temp')#\#cffile.serverFileName#.jpg" overwrite="yes">

Answer 2

It sounds like the image found in this line <cfimage source="../photos/#qryCampers.std_image_filename[iRow + iCol]#" action="read" name="cardImage"> is not a valid image format. Are you sure what it is trying to read there is an image?

Answer 3

Have you tried using "isImage"?
<cfif trim(qryCampers.std_image_filename[iRow + iCol]) neq ''
AND isImage('../photos/#qryCampers.std_image_filename[iRow + iCol]#')>
I agree with #Leeish that the CFImage tag is getting something that it doesn't recognize as an image. I have had time when I've had a jpg that was marked as a jpg and I could view it in a browser but then I tried to pull it up in photoshop or something similar I found that there was a aheader problem in the jpg itself that was preventing cfimage or cfx_ImageCR (which I prefer).
