What would cause this error? E_WARNING: exif_read_data(upload_OEkvSF): Illegal IFD size

Hi equinox,

This is a bug we're aware of - the error itself is relatively benign, and is caused when uploading images that were created or compressed in certain ways. We are working on a more permanent fix, but in the meantime, you can silence this error by adding an "@" to line 177 in /cmsb/lib/images_functions.php, which should look like this:

$exif = @exif_read_data($imageFilePath);

Let me know if you have any further questions!

Thanks,

One other thought on this, Daniel...

Is there any, or what is the, danger of turning this error off? Are there other situations where this is needed and we should be warned of something? Thanks.

Hi equinox,

In this specific case, there is very little danger in turning off the error. It relates to reading data from an uploaded image to see if it should be rotated (e.g. a photo taken in portrait may have the orientation saved to it by the camera), so the theoretical worst case scenario is that this rotation does not happen. However, this error doesn't specifically indicate a problem (the rotation might still work even after an error here, and the error can show up on images that don't need to be rotated) - so it's not very helpful for users to see it.

Thanks,

Thanks for the clarifying, Daniel.
