I curious how you are getting any results from WGET from secure (https) pages. My experience with WGET is that it fails in general with https, but does a remarkably good job with http sites. I've noticed some issue with jpgs, pngs, etc., as you too seem to have found. For these reasons, I switched to cURL, but you have to parse out links to direct cURL to the pages you want to harvest. A neat feature of WGET is it can grab an entire site.
Oh, and quit downloading "pron" whatever the hell that is. (Reread your original post. :)
