Ok its a bit complicated, dont bid unless you understand requirements.
I have a flash application which runs on a linux server. I need someone to take a .net photo application and install it on a seperate windows server.
The windows server will need to receive commands from the linux server (photo), then take the photo-apply the photo effect, and send a command back to the linux server for the flash application.
Request to http://windows-server-domain/some-path/some-image.jpg will reponse with image from http://linux-server-domain/some-path/some-image.jpg + oil filter.
So essentially, the web service accepts request from our linux server, takes uploaded image from your current system like http://your-domain/some-path/image-id.jpg, then applies oil effect and generates response with oiled image back to flash.
