Another Photoshop book question.... help me please

I recently bought Learn Photoshop CS in 24 Hours (or something like that). It was the only Photoshop book my my local bookstore :frowning: but anyway. This seems to just show you how to modify photo’s but I want to know how to make web graphics like the unbelievable . I know that it is probably a 1000 times harder but I am a freshmen in highshcool so i figure it would be awesome to start learning now and in colledge maybe senior or junior year, be really experienced in Photoshop.

So does anyone know a good book that shows you how to create graphics, not just edit photos. I seem a lot of awesome designs made just in Photoshop and I want to know what book to get that shows how to make these great graphics. Thanks for reading all this.
