This version only works for Windows Live Writer Beta 2 (and later).

Better implementation of the WLW B2 fix (this time using the AssemblyResolve event)

Added Preview Feature
Now you can preview how the picture/thumbnail will look prior to inserting it (to make sure the selected thumbnail size is what you had in mind, etc).

Changed initial plugin behavior - Canceling the file selection dialog also cancels the Upload Picture Dialog
So now you don't have to click Cancel twice...

Added Plugin version number to the dialog Title

Added Visit FlickrNet linklabel
To give additional credit to the library that without which coding this plugin would have been much harder...

Fixed layout/dialog resize with the Insert As label and combobox
