 This has been a long standing problem for me.  I am having problems with
 uploaded images and am unable to properly troubleshoot because the image
 upload feature does not display errors.

 The root problem is that the image upload feature does not display error
 messages.  The symptoms are that thumbnail images are not being generated
 and my theme (AutoFocus) cannot display EXIF data for images.  I have
 switched to the default theme, disabled plugins and performed other
 troubleshooting activities
 (http://wordpress.org/support/topic/164999?replies=1).

 Scenario:  I am uploading a 800x600 143KB color JPEG image.  The Flash
 upload tool shows the status bar going to 100%, Crunching... and then
 stops once the bar clears itself and the "Save all changes button"
 appears.  Nothing else happens.  No image thumbnail is displayed, no image
 information (titles and descriptions) is displayed.

 When I close out the 'Add an Image' window and reopen it I can see the
 image in the Gallery but there are no resized images available (thumbnail,
 medium, large) and the full size dimension is listed as 0x0.  When I
 choose to Edit Image I get the error "Image data does not exist. Please
 re-upload the image."

 I repeat the upload process using the browser upload method. Once the
 image is uploaded the 'Add an Image' window is cleared and is left blank.
 Closing the window and going into the Gallery yields the same results as
 the Flash method above.
