hey guys.. how to remove picture backgroud..? if I copy it.. it always has white background on it..

Drag the image on the workspace..
Create new canvas with any dimensions and choose background as transparent instead of white and click OK
Then drag the image on the canvas..
Use magic wand to select the unwanted part and hit delete button to delete the background and hence you will have only the image that you want with transparent background instead of white
Another way:Instead of using magic wand, you can use pen tool with rubber band option activated and select the outlines of the image that you want.. then go to paths tab and click on load path..
then select rectangular marquee tool and right click on the image and click 'select inverse" then hit delete button and you will have your image with a transparent background. when you save it as jpeg, you will get only the image and no white background..
