Well, you can either disable no right click, (look in the faqs section for a how-to). Or, there is a way around the no right click without having to disable it.
To get to url to just the image (which is what i think you want) you must right click the image when uploaded, and go to properties and get the link there. So to right click it and get this...do the following:
Right click the image, and hold down the right mouse button (even when the message pops up about no right clicks, keep the mouse button held down). When the message pops up, hit enter on the keyboard so the message goes away, and then once its gone, let go of the mouse button and your normal right click options will come up.
