software for icon design.

Hi All,

I have designed the logo for my website on a paper. So I need a software where I can make this logo in gif or png or etc format.I need easy one as I am not a graphics designer I just need to design my logo.

I know Photoshop might be the option but is it easy to use. Also is it common to take the photo of the drawing on paper and then put in the website. I am feeling it much easier than designing on the software. I am might be silly here 

Thanks for reading..
