A great resource for learning the basics of Adobe Creative Suite applications is a website called TutVid.com. This site provides short tutorials to learn graphic or web design skills. This is a great resource for not only the newcomer who is learning the ins-and-outs of the robust Adobe product lines, but also for anyone looking to touch up on how to use these products if you have been away from them for a long time.
The tutorials are very short, anywhere from 5-20 mins. They also range in terms of experience. Some are very introductory level, while others provide an advanced knowledge of graphic design. It is strongly recommended that you follow along by mimicking the tutorial (dual monitors works best.) This will help you to get more hands on with product and increase your skills.
Your graphic and web design skills will be improved in no time, and oh, did I mention that all the tutorials are FREE!
