you need to modify a photo and you don’t have the tools to make it, you can do it using an website that
allows you to modify a photo, and then also to save it.
the website is http://pixlr.com/editor/ the interface is similar more or less with GIMP or photoshop, having the tools for editing photos, you may wanna give it a try.
will we have all in the future a google laptop that save all content on-line, maybe 🙂
