Challenge with .png graphic uploads - causing error "(An unexpected error occurred: #1414) self.parent.reloadIframe('teaser_graphic_iframe')self.parent.hideModal();"

Hi Codee,

Thank you for the report!

I've done some looking into this issue, and couldn't find a conclusive cause. This appears to be an error coming from PHP's image creation library (GD), which may signify something unexpected to do with your particular PHP installation, or the PNG files themselves. If they aren't sensitive, could you attach one of the PNGs that has given you trouble so that I'm able to run some further tests?

Thanks,

Hi Codee,

Thanks for the additional info. A curious issue to be sure - uploading those images to my test environment doesn't produce any errors, so it points to something related to the specific libraries available on the server. Could you test out the following patch for me? In /cmsb/lib/image_functions.php, replace this line (at or around line 42):

case IMAGETYPE_PNG:  $sourceImage = imagecreatefrompng($sourcePath); break;

With this:

case IMAGETYPE_PNG:  $sourceImage = @imagecreatefrompng($sourcePath); break;

This should hopefully silence the error. As the image still uploads correctly, that may be sufficient.

Thanks,
Daniel

done. Thanks, Daniel. I noticed the .jpg was already set to suppress jpeg errors. Is that how the core file is supposed to be set?

Hi Codee,

Yes - it appears there was a similar issue that came up related to uploading invalid JPEGs. We prefer to resolve error messages without silencing them, but sometimes it is unavoidable!
