    Not working PDF export for image files with capitalized file extensions (eg. JPG)

    Asked by tammyhu on June 24, 2013 at 05:11 PM


    The PDF export function of responses does not show image thumbnails if an image has a file extension that is capitalized. I noticed this that .png showed image thumbnails in the PDF export.

    However, a .JPG did not export with a thumbnail in the PDF. I renamed all .JPG images and edited the submissions to have .jpg, and then thumbnails started to show (as expected).

    Just letting you know. Would be great to have this bug corrected by your engineering time.
