For a limited time, SitePoint is giving free copy of Photoshop ebook called “The Photoshop Anthology”. This book will cover different web design techniques by using Photoshop.
What you need to do is just provide your email address, and they will send you the download link. There are two format of ebook (high resolution and low resolution). I suggest that you download the high resolution version, although it may take longer time. But it is worth as you get higher quality of graphics and images.
I had use my yahoo mail in the email form, but unfortunately it take few hours before i can get the download link. You can direct download the ebook from sitepoint without register (Thanks labnol for sharing the link).
