This site is "for those how code", here we help to solve specific problems in code you have already done.

As CPallini says, Starting with Google search gives you a lot of responses, always check before simply asking

The only kind of comparison you can expect by computing MD5 hash code of images is if images are identical or not.
Be aware that whatever the method you use, with hash values, you can have collisions, it is when 2 different images give the same hash value.
