I am currently investigating an ethereal capture file somewhere in the range of 3 MB. What I am looking for is a tool which will extract all the image files in that capture file that were fully transferred during that time.

Perhaps a tool which would rebuild each conversation and save them all as HTML files would work, since the image data would no longer be fragmented (hey - I need a tool that does that, too)

Does anyone know of a tool like this, which could rebuild fragmented image files (such as the case with an ethereal capture) from unrelated media?
