[BUGFIX] Ensure imageLinkWrap works with UTF-8 filenames

The unset($info['originalFile']) introduced in #90565
broke an access to that array key below in the method.
This leads to the situation that files with UTF-8
characters are not found anymore since the imageLinkWrap()
method is fed with an encoded version of the filename
and not the original file object anymore.
The patch parks $info['originalFile'] in a variable
to access it for imageLinkWrap() again.
