Comment 2 for bug 1205132

ImageMagick mogrify -resize also generates an error notification but thankfully waits until all images are processed prior to doing so. However, the result is an image that from the point where it is thought the image ends on to the bottom of the actual image, it's gray. I'm working with several variations of C Curl download scripts to see whether that might be introducing the problem, but thusfar have found nothing. If the downloaded image is left untouched, it shows no indication that anything is amiss, but only after resizing.
