It'd be cool if the site included a WebGL globe like Cesium that could be used to display images from posts or galleries. Getting Cesium to display a single image in normal equidistant cylindrical projection is relatively simple. You just give it the URL, and optionally an extent (if it doesn't cover the full globe).
It does have a problem if the image is larger than the largest texture your OpenGL implementation supports. This can be resolved by providing a tiled image service like WMS or TMS, which would also be cool for providing a way to do 'zoomable' maps (via OpenLayers or Leaflet). It's rather more complicated though as it would require something server side like GeoServer or GDAL2Tiles to provide the tiles.
