How do I change a photo to be more than 300,000 pixels?

I'm using Microsoft Auto collage which requires images to be ';more than 300,000 pixels, and which have both dimensions larger than 480 pixels.'; How can I do this?

The only way you are going to even consider enlarging an image with minimal loss to details is with a program called Genuine Fractals ( http://www.imaging-resource.com/SOFT/GF/ ) %26lt;--- for a review on this.



Anything else is using color interpolation which is interpreting a relationship to the associated surrounding colors and assuming the best match... image quality goes to the toilet this way.How do I change a photo to be more than 300,000 pixels?
From Microsoft's site:

For example, a 640 x 480 picture can be loaded by AutoCollage, but a 1000 x 400 picture cannot because 400 is smaller than 480.



You can do a simple resize in Microsoft Paint.. free

it's on your computer already
Make sure width times height also = 300,000
Sometimes..... if you enlarge in small steps, the image doesn't get as ruined. ... sometimes..



A lot also depends on how small your image is to begin with. If your trying to enlarge captured thumbnails, say something around 80 pixels per side, forget it. It's just too small and there are not enuf pixels for the re-sizing to work...



In fact, if the image is 2 or 300 pixels per a side it most likely is too small to enlarge, as you are finding out here.



Try small steps at a time, it may work better than one big step..
