The whole "virus in jpg files" thing started around ten years ago:

But I have never heard about any cases of jpg's that actually has harmful code integrated, only false positive reports by antivirus software.
Anyway, it's good to hear that WinAmp has new owners. I personally use WinAmp for music, VLC for videos and IrfanView for pictures on all my Windows computers. And I only use classic skins with WinAmp.
