I think the point here is not how to save a picture - Unlike the previous given answers I don't presume that you don't know how to do that.
I think your question is in regards to potential copyright issues and your wanting to reproduce it maybe for your own use or to resell at a profit?

The answer is that although Google images has the images indexed in their engine - The intellectual property still belongs to the original owner. Google has an opt-out for webmasters to exclude images appearing in Google images. If you as a webmaster publish such content on your sites then it sure is easy to steal it but is still illegal to reproduce it without the owners express permission.

There is no such thing as a global or "international copyright" protection scheme, instead each westernized country have there own similar individual laws to help protect owners intellectual property. Also in most cases each individual country will cooperate in bringing about an infringement suit where necessary - please be aware!

right click on the picture
and then ''SAVE PICTURE AS'' where ever u want in ur pc
