Yes I have used it as a template for my own implementation.
I discovered that the problem is that CE expects the GetImage file to be in the same directory as the ImageEditor. That is why it did not work. You should implement functionality to allow the image editor to work with relative urls for the gallery... When I return that the Image can be retrieved by the "GetImage.aspx?..." file that same file should be used to display the image in the editor and the gallery. That does not work in the current version...
By the way. The sample projects are VERY poorly documented... You should avoid lots of support issues by producing better documented examples... If the CE is as poorly documented I can understand why bugs seems to appear everywhere, as noted in theese forums...
