wp_read_image_metadata is looking for invalid EXIF data

[theMikeD]

wp_read_image_metadata() is used to determine which info found in the the IPTC and EXIF header for an image gets inserted into the database. Unfortunately one of the tests it's doing is looking for an EXIF entry that doesn't exist.

From everything I can determine there is no such tag as EXIF:Title, which is being looked for on line 341 of wp-admin/includes/image.php

This test should be removed.

This is correct - EXIF Title indeed appears to not exist, which makes this piece of code unusable. I suggest that we should remove it as unnecessary. Also, nothing further should be done, as in the lines below, EXIF ImageDescription will be set as title (if not longer than 80 characters). Submitting a patch with the removed code.

In 31462:

Don't try to read a non-existent Exif:Title tag in wp_read_image_metadata(), as it's not a part of the Exif standard.
