Exceptions while uploading an image in CMS

Case 1 - When I upload the image (copyof2cms7.......) I see below error on front end and attached exceptions in console. Also I am not expecting to see "an error occurred while parsing image metadata" on front end or the exception in the console.

File copyof2cms7_5074_BandWr.jpg is too large, the maximum allowed file size is 500K.
An error occurred while parsing image metadata.

Case 2 - When I upload the image (cms7_5074.......) I see only below info message in front end. No exceptions in this case

Image cms7_5074_BandW.jpg is too high, max allowed vertical pixels is 1,280
File cms7_5074_BandW.jpg is too large, the maximum allowed file size is 500K.
