Both will allow you to pick sizes for pictures....Blogger has five options, small, medium (which is what these picture are), large and X-large, along with "original size". Live Writer's sizes are basically unlimited....you just click on the picture, grab a corner and make it larger or smaller. It is easy to put in a border too, and I have not found how to put in a boarder with blogger's editor. Live Writer also easily allows for picture to be side-by-side, and allows for tables, and allows for quicker linking...the list goes on and on.
Don’t know why, or for how long Google, who owns Blogger, will allow Live Writer to continue to work. My guess is that many blogs have gone from Blogger to Wordpress, and they gave in for now…probably until Microsoft allows Live Writer to become OpenSource and the security the Google wants is created for Live Writer. Microsoft has pretty much washed their hands with Live Writer from what I have read.
We are still in Oregon...rain today and travel just wasn't in the cards. Will be back in Sacramento tomorrow for awhile.
