Win7 x64 Screensaver Questions/Issues. No 'Stretching'?

Couple of questions for the experts here....
Windows XP's Screensaver [custom] had some very nice touches that do not seem to be replicable under Windows 7. If one had a photo selection, under XP that set could be used as a slideshow for screensaver, and the images would be cycled in a 'corner to corner' fashion [nice little touch], and the Images would all scale to the full dimensions of the screen. Under Windows 7 options, I can setup a personal slideshow... no problem there, but:
1. I do not see ANY options for how to display transitions from one slide to other.
2. The images do not scale to fit the screen. They display in some predetermined resolution & scale that I don't see any user-adjustable settings for
3. By Default, when using such a personalized Screensaver, I get a rolling banner across the bottom of the images, Displaying Date and Time. How do I shut that thing down?

All help gratefully received!

Use backgrounds not screensaver which is a dated concept.

You can make an impressive slideshow using the spectacular Win7 backgrounds - all 120 regional editions backgrounds can be downloaded off the web: http://www.mydigitallife.info/2009/0...free-download/

Rightclick the Desktop to Personalize.

To reassert my questions:
- Where is the control of that scrolling banner? I know where its not... its not in the Windows 7 Screensaver settings - its some other widget
- Don't care to use M'soft's pictures. We like our own photos.
- Is there a way to cause the slideshow images to scale up to full screen?
