Photoshop - changing the size of an image?

I have a 30 day trial version of photoshop right now and I was wondering how you change the size of an image on it?

Like, when you use paint you can just get the corner of the image and change the size.

But in photoshop it's different. I have Adobe Photoshop CS3 Extended, does anyone know how to change image sizes?

Hit ctrl-T to transform the image.

Then grab the corners or sides and pull.

Hold the shift down to keep it proportional.
As "H P" said... you should right-click on the top bar of your image and choose "image size". There you can either reduce the actual height and width or go for decreasing the resolution.

Good luck and have fun!
you need to click on the top menus where it says image then image resize
