[Plugin: W3 Total Cache] 404's old cache versions

I get lots of 404’s in my site logs of cached versions of images that no longer exist i.e. ../wp-content/header-images/P1220425_stitch-carousel-central-park-nyc-pano.jpg%3Ff22064 (image is in “header-images” directory to accommodate a random header image plugin)

Is there an easy way to auto redirect the expired version to the newest (cached?) version?

Many thanks for any help and for a generally very useful plugin
