Girls, What does it mean when my female coworker sends me these pictures?

One of my coworkers has always been touchy feely with me ever since I got the job. She "accidentally" touched/smacks my ass whenever we're alone and yesterday sent me these pictures. I have no idea wtf is going on. I mean... I find her attractive and everything but I don't know if I should do anything or like what I should even do if I DID want to do something. Girls, can you explain and help?
