How do you Resize an Image for the Web ?

hello everyone,

I need some help here, just got my corel x3 a couple of weeks ago and i was wondering if there is a simple way for me to resize a cropped image to a specific width in corel-paint ? ...so that i can save it as a JPG and upload to a website.

I used HP software before, it basically gave me a little window where i would key in the width of the image (in pixels) and it would resize it for me in porpotion. I can longer use the HP software because it does not work with my Vista laptop. Sad 

 

sorry, i played around with it in photo-shop, got as far as cropping the image, but can't figure out (a simple way) how to resize it.

 

your help is greatly appreciated.

 

thanks in advance.
