can be done in seconds with Paint.net,
Load the image into the program then using the magic wand tool select the parts you want taken out,
then click on the arrow tool and move the part u don't want off the picture,
Repeat until you have what you want.
When using the magic wand tool you may have to adjust it a little, try for around 50%
save as a PNG file.
Or if u wish i could do it for you just post the pic on here.
