We have image fields (stored in database) in a form that are set to show reduced size thumbnails of the images. All is fine in the development environment where the images and their thumbnails appear in the tmp directory and are displayed in the form as expected. However, when posted to the production site, the thumbnails do not appear in the default /-lib/temp directory and are not visible in the form ( the full size images are still available when clicking on the image link, that should have been the thumbnail). We have checked the tmp directory permissions and made sure that they are full open for read/write for all users.
Looking for any insight on how to fix this problem. Thank You.
