I got photoshop trial and I know how to do that but the pictures are realy big How do you make smaller crop and background trans parency?

Now I read the instructions how to make a character like 100 times but I don't get how to make a picture for the character. I need some help making sprites for a character name jujimufu. You see.....I'm a trickster and I want to make a game full of tricking charcaters but I don't know how to make a sprite or a picture of the same person in moves can someone give me a program or some advice please?
