No Toolbar

If you don't want to show the toolbar, use the following code. You might have to tweak the different parameters a bit to get the best result in your situation + when you change the size...:

<div style="position:relative;top:-20px;overflow-y:hidden;overflow-x:hidden;height:440px;width:580px">

<div style="position:relative;top:-50px;left:-40px;overflow-y:hidden;overflow-x:hidden;height:100%;width:100%">

<iframe style="border:0px double " width=650 height=510

scrolling="no" src="https://picasaweb.google.com/pieter.roggemans/ScrapbookPhotos#slideshow">

</iframe>

</div>

</div>
