The first one is an early pic of Josh with something going on in the pants pocket area. Prolly just tissue or something, though. Tha's about as close to bulge you're gonna get from him.
The others are just cool pics I found. He's channeling Elvis in the third one.
THe last one is his long-time lover, Brody Dalle. Formerly Brody Armstrong, now estranged from her other punk-rock man, Tim Armstrong.
