A calendar-based gallery
Callery: Gallery Calendar — description
Have you ever wanted to view a day's photos without traversing a massive collection for the right heading? Have you ever wanted to remember an event from previous years and social media didn't pick the right photo? Callendar is here to provide a simple calendar that display's photos taken on that day.
Coming soon: EXIF editor for when photos simply don't end up where they belong.
