Here’s a little script inspired by a question on the list. Drop this file into a folder full of JPEG photos on your server, and you have a photo feed. To update, just upload more photos to the folder.
Link to it as an auto-discovery feed, like this (in the head of your page)
I just updated this, based on some suggestions and code from Tim Plumb.
It now uses IPTC Title or Description (if present) to create the headline, and falls back to the filename if neither are there. It also can serve PNG and GIF, along with JPEG images.
