Technology has really come a long way. Apart from taking and storing our photos digitally, we can edit them. There are a number of photo-editing softwares which we can buy from shops. However, since most of us edit our photos as a fun hobby, we don't feel the need to spend a few hundred dollars on a photo-editing software. Luckily, there is also a range of free photo-editing websites available to us.
My favourite one is Picnik. You can edit your photos without the fuss of creating an account/signing up with them. Even without the premium edition you can do lots! From changing the brightness of your photo to softening or fading it.
Photoshop (the online version), is pretty good as well. It also gives you the option of not creating an account and simply editing your photos. If you wish to store your photos on their site, you'd definitely have to sign up. There are a few things that Photoshop can do that Picnik cannot, vice versa. If you have the time, you should play around with both of them and decide which one you like best... or use both!
The website that I use to store some of my photos (for forum use), is called Photobucket. It does have editing tools but I find them inferior to Picnik and Photoshop. What I like about Photobucket is that it generates links and codes for my photos that I can easily copy and paste. Besides that, with so many people uploading photos, you get to browse through millions of them. Among them, you'd more than likely find a good photo of your favourite movie star or a beautiful scenic shot that you want a copy of. Photobucket also holds photography competitions some of which you can win cool prizes from!
There are plenty other websites for you to try. I'm simply too content with the three that I have listed to explore others. Other photo-storing websites that I know of are Flickr and Shutterfly. You must create an account with them as well if you want to use them. Shutterfly is a bit different whereby you can create photobooks and buy it from them. If you wish to download a free photo-editing software, you can try Picasa. Apparently, you can create amazing collages with it!
