First, use the lasso tool to select the part you want to cut out of the picture. Trace around it then press ctrl+x to cut that section out. After that, you can either:

1.) paste the part you cut out above the new background picture ( you may need to resize a bit)

or

2.)paste the part you cut out back into the original picture (which will create a new layer), delete the 'old' background (which should be the layer underneath the part you cut out), go to the 'new' background image, select the entire thing, copy it then paste the new background in a new layer UNDERNEATH the cut out layer.

...eh the first one is easier..hope that helped...good luck =3

Absolutely! Plus a whole lot more...These are some things I've used Photoshop for over the years: Automatic color correction Removing and replacing backgrounds Duplicating objects and people in photos Changing someone's hair, eye or clothing color Colorizing one object in a black and white photo Changing day into night, and vice versa Whitening teeth & removing skin imperfections Making photos look like drawings or paintings Creating shiny reflective buttons and icons for websites
