Hi Alan,
I am strangely interested in taking these sorts of view of my memories. I suspect My ‘On this day page’ is the one I look at most on my blog.

It would be nice if Flickr provided days & months via the api. I was pleasantly surprised as to how fast I get the pages up. But perhaps being on the same network as the Pi;-)
It did take a few minutes to build the database in the first place.I did this on my mac. For my Flickr I had to make 23 calls getting 500 photos at a time. I think yours would take a lot longer.
I’m just using the pi cause it is easy. I am sure you could do it on any hosting with php. Also you could do it with a MySQL database I am sure. I’ve only used on a couple of times and in each used your wrappers for accessing the database.

happy holidays to you and yours!
