You have Photoshop, and the program pretty much has every tool possible for picture editing, so of course it is possible to sharpen the images. BTW, I don't mind if you can do it later, take your time.

See the small guide here for image sharpening.

P.S. Do not change the size of the images. Keep them at 660x360px.
