Choosing the right image file format is very important in terms of loading times, SEO etc. A short answer: If you don't need transparency and got "normal" images just go for JPEG.

PNGs is perfect when you have an image with rapid transitions between colors that need to remain sharp after compression. So, if you want your site to load as fast as possible, and you don’t mind sacrificing a bit of image quality while compression, JPEG is the best image format for your needs.
