thank you james for all your trouble.. wscript still gives me the same error @line 75, it could be a problem on my system cause of certain restrictions i have for vbs and vba.. hopefully it works for others.
the thing about not saving all content in mht files like images etc is normal..even when saved from ie.. i'm not sure how it works.. sometimes it does save all the images inside the mht file and sometimes not and needs to fetch them from the website.. i think it could be related to the href address for the image.
for example if image href is internal in the site
href="/img/pic.jpg" then the image is saved internally
but if href="www.otherwebsite.com/ads/banner.jpg" then the image is excluded from the mht file but with a placeholder for it to get it from the specified site.
