I was thinking from a deployment point of view its much easier to have a single application with a little bit of scripting to go with it rather than having extra executables involved. Ideally I want something that would allow me to "paste" an image into a webform and with the current state of technology that doesnt seem very likely to happen any time soon
The underlying implementation of something that might work could be a context aware "paste" operation ; I'm not sure if clipboard notifications extend to paste or if they just work when data is going into the clipboard...
If it was possible to intercept the paste event when it is going to a program that doesn't accept an image datatype then a bit of scripting could make it all "just work"... either by creating a file (on a local or network filesystem) that is linked to or by uploading to an ftp site or an image hosting site
It sounds like a simple requirement... I just haven't thought of a good way to do it yet
