I just stumbled into
PhotoBlox.
It is an image viewing application that can be embedded into a personal blog template or Web page. It totally relies on Flash's multi-media capabilities and
Laszlo's ease to dynamically fetch external data and display it. The application loads fast, works in almost every browser and looks great in multiple sizes. For applications like this, none of the other RIA solutions that I know would fit the bill. Well, maybe
Flex would, but I doubt that anyone would pay at least 14400 € in licensing to be able to run a photo blogging tool
