Found a picture online and want it bigger or better quality?

I have been doing a website for SBCC  TAP and have run into problems were I find an awesome picture BUT....  the picture is to0 small and if a make it bigger, it gets pixelated. I found a website that solves my problem. This website is called TinEye.  The website finds pictures relating to the ones you need. In order for it to work you must paste the picture URL or upload it to TinEye. Then, TinEye searches the internet to find related pictures. Walla! Problem solved.
