Ciaran,
When use the physical path to specify the Image gallery path, the physical path must be part of the current web site.
Use physical path:
<security name="ImageGalleryPath">c:\inetpub\wwwroot\uploads</security>
For your situation, I suggest you create a virtual path ("/uploads") and points it to D:/IIS Projects/publicWebsite/Uploads.
And use the following methods:
//use the app-based path
Editor1.Setting["security:ImageGalleryPath"]= "~/uploads";
//use the absolute path
Editor1.Setting["security:ImageGalleryPath"]= "/uploads";
That will resolve your problem.
Hope it helps.
Let me know if you have any further questions.
