I have 60 images of Sunglass, want to give a grey gradient effect on the bottom of the images.
will someone help me to do this?
Thanks in advance.

I don't know what you want. You can create an image with "gradient:" or "-sparse-color" and append that to your image.

Perhaps you can show a mock-up image.
