I have Ubuntu 11.10 installed along side Windows, when in Windows, the situation below does not occur....

When trying to add pictures to some programs, such as Facebook, Wix, etc... I have noticed that the upload feature will not show some images in jpg. However, if I go into the folder that houses them, they are there.

As this is not specific to just one type of site, I believe this may be an Ubuntu issue. Has anyone else had similar issues?
