[quote]The Replace File dialog makes it easier to identify the largest and newest of the two files
The "clock" icon () indicates which of the two files is the most recently modified (the newer) and the "size" icon () indicates which of the two files is the larger.[/quote]
Please, add one more visual icon for image dimensions (416x27 vs 1213x526 on this screen) in "desc" field!
Also, all icons can be unified by a single icon - "Plus" or "Check mark" icon for example. But it is not so important!
