Photoshop

I want to be an expert in photoshop cs4!!! plz tell me the way!!!

Check youtube for tutorials and also photoshopTV is a good resource. Also Layers Magazine website has tonnes of tut's

Good luck

Work through a ton of tutorials. Look for Photoshop books on Amazon with good ratings. I like the Classroom in a Book series, but you may find something that suits you better. Find images and graphics you like and do your best to recreate them. Don't be afraid to experiment with the tools!
