I sometimes need an equirectangular photosphere viewer for my own local 3D spherical images, but there are no easily acquired cross-platform desktop-app viewers. It turns out that with an advanced 3D JavaScript library like Pannellum available, a browser-based viewer becomes practical, not to say easy.

The idea of this viewer is that you:

• Drag & drop an equirectangular photosphere image into the gray frame below, or
• Click the "Browse" button below to select a photosphere image from your files,

and the image will be displayed in this 3D viewer with navigation controls.

This page doesn't interact with the Internet after loading, it's just a convenient, local-image viewer.
