Random photos, or photos selected by date or category, are provided by the
#randominage pagelist format.
All photos provide a two level click though to a single larger version, and then through to the original image. This is supported by the site image template.
Web browsers don't natively support image rotation. The orientation data is available in the EXIF tags included in the picture. Natively, a picture is always in the landscape format. To fix this for the website rotate the picture before uploading, or rotate it and re-upload it. To rotate an image use an online tool, or download a tool such as FastStone Image Viewer
