FCP has no problems with JPEG files at all. Just makes sure those JPEG and PNG files are not too huge. I'd go to Digital Rebellion's web site, download the free Preference Manager app, trash your FCP preferences with it, see if that clears things up.
You may also try going into Tools > Render Manager, and delete all your render files, re-render from scratch, to see if it's a corrupted render file.
