If you have used Live Writer on Vista and moved to Windows 7 (as I have just done). You may have found that the insert image on Vista allowed you to specify a URL for the picture on the Web. Under Windows 7 there is no way to do this.
The following is a link to the “workaround”. Simply put, on the web page of the image you want to link to, “copy” the image (righ click, the copy). In Writer just “paste” the image into Writer. The copy/paste will actually generate the link to the image on the web.
I’ll give some thought to writing a plug-in which does URL’s the old way. I suspect that with a bit of “low level .Net voodoo” I could aggregate the existing image manipulation functions. Or, in non-technical, hijack the existing function and put my own façade onto it.
