How to view loaded website content? lol

ok this is a fairly simple question, but for some reason I cant figure it out.
i saw a gif on a website and for the life of me cant find it. I really wanna use it for school project, and I know website content is usually stored in a folder.
what folder is it stored in? I used to do this all the time but now im clueless as how to find it.
Answer #1
If anything, it would be in your cache. Searching for it manually would be hard so you should use the firefox content browser thing. Not sure if it comes with firefox or its an addon because i dont use FF anymore, i use chrome. But yeh, in your cache mate. So search google for cache browsers that show you a preview of what file you click on. Dont forget to sort the files by ‘type’ and then browse to the .gif extensions
Answer #2
NeoDownloader 2.4 can snag GIF’s from websites. Or try URL Snooper. I think you can configure it to find GIF’s as well as audio and video from websites.
