Read URL image size - Multithreaded -- 2

Hello, I want a program that read URL image size. I want the program to send 2 URL image size reader requests in one time for 1 URL. and if the two requests "size" is match. We consider this one as valid and output to a textfile "[login to view URL]" If it not match. We consider as invalid and we skip it. and go to next. Example (Valid/Invalid) REQUESTS below: ------------------------------------------------------------------------------- [login to view URL] -> Image size: 1111 [login to view URL] -> Image size: 1111 = Save "Mike" to [login to view URL] ------------------------------------------------------------------------------- [login to view URL] -> image size: 14566 [login to view URL] -> image size: 64464 = SKIP! go to next URL name. -------------------------------------------------------------------------------- So.. *Load [login to view URL] *URL is standard. *Start/Stop/Pause. *add delay between requests. We will load names from [login to view URL] - and I need this to work fast I want it work as multithreaded. As easy, as simple as that. That's all the requirement.
