Those are my photos. Just borrowed a nicer camera, is all.
The wood background ones I took with the uke on my living room floor. The headstock is set against my bed sheet.
The uke is essentially new, which could explain why you might mistake the photos for stock photos. I didn't think it'd help sell it if I stood in the frame. I had to crop my toes out of the side view pic.
FYI, if you want more people to consider this uke, you should take a picture of the uke along with a piece of paper that lists the current date, Ukulele Underground, and your UU name.
