Spherical Images

Hey folks, would appreciate a little info on a subject

I’m having a lot of difficutly finding spherical images for use in rendering.
Maybe it’s something very obvious but I can’t find em.
Anyone know where they’re hiding

Rarely see them. Check CGChat. People will post freebies there occasionally. Also, might want to check this link: Digital Urban: How to Create an Aerial Panorama from Google Earth

Are you referring to panoramic images for use as background? Or high dynamic range images (HDR) for use as illumination?
