Managing Re-direction on WordPresss


I have recently re-built an existing eCommerce website using WordPress.
I have added re-directions on all existing pages using a plugin.
Upon checking the 404 error logs I found that there are many image link.
Note that we have a lot of unique images on our website and I do not want to miss that traffic coming from image search.

How do I manage the 404 coming on for image URLs?
