Would I need to credit an image like the one in the hide box below?
No; that's a meme/reaction img
It'll be downright impossible to source and even then there are probably multiple images with the same captcha all of them could be 'claimed' to be the original source.
Most images like this usually come from sites that have anonymous tags or no information on the uploader is available - and even if it is chances are they didn't make the original. Even the watermark used there is impossible to read. God knows where it came from; and to be frank images like these aren't exactly 'art' anyone can slap a captcha on an image -granted that it's not a drawn image that someone took a considerable amount of time to draw. As of such I have my doubts that it follows the whole 'copyright' law due to its very nature.
