The MobileBooklet.com site is developed and tested mostly on the Mac OS using the Safari and Firefox browser. I was surprised to find out that booklet cover image upload did not work on Internet Explorer.
Safari and Firefox uses the following mime-types for image file uploads:
- image/jpeg for jpg files
- image/png for png files
Internet Explorer uses the mime-types:
- image/pjpeg for jpg files
- image/x-png for png files
I was happily creating mobile booklets using Safari and Firefox, so the error was not discovered until someone using Internet Explorer reported the error. (Thanks William!)
So, I made a minor change to ensure the MobileBooklet.com website will accept the following mime-types:
- image/jpeg
- image/pjpeg
- image/png
- image/x-png
Problem fixed!
MobileBooklet.com is built using Ruby on Rails and the image uploading is handled by the Paperclip plugin.
