Ok professional web developers. im new to buying images, please help out.

When buying stock photos for a site.

What kind of copyright and license am i looking for?

What pixelxpixel and dpi should i aim for (suitable for websites)?

What are some good cheap stockphoto sites that are good?

thanks alot.
Vinh.

U might want to have a look at gettyimages.com , corbis.com
Both r good. U'll find all the info u need on licensing on their sites.

Gettyimages is good, filter out the RM (Rights-Managed) ones though, because they cost heaps. Royalty-Free images from there are about $19-$60.

www.istockphoto.com is a free site you may be interested in, if you're not too fussy.

As stupid as this is going to sound, there are ton of free images on a subsite of Microsoft's. The downside is that they're a bit of a pain to transfer to PhotoShop or any other document:
