Symbolic links and timestamps

I have a weird question. We have a server with symbolic links that are linked to images. I run a script once a week to find all new images with the -neweronly command. Here is a sample below:
The problem is the symbolic link timestamp does not change when a newer image is linked on the ftp server and it is not returning newer images.

Is there another command that I can run to check file size or the source image timestamp date?

Couple of background information items. There are many images on the links server that I do not want, so syncing them is not an option. I have a batch file that creates my WinSCP script file on runtime to just check the images that I want.

Appreciate your review. Thanks.

Thanks for your suggestion.
