Weird 4.2 Gallery Issue

When I export a picture from Dropbox, it shows only the old version of the picture even though I checked to make sure it was the new version.

When I download it from email, it will show up in the Download album but when I move it to the Pictures folder using the file manager, it doesn't show up in the gallery.

When I open the picture from the file manager with the gallery application, it works, but the picture's kind of blurry.

What's going on?
