I have used this photo editor to good effect, adding a tonal filter to my photo, and downloading the photo in its full size, without having to open an account. So far, it is free and easy to use. I hope that doesn't change! I noticed that it has tools for cropping and some other tools I haven't tried yet. It all looks great!

LunaPic
LunaPic: This might be an excellent free tool. It provides the ability to rotate by degrees instead of just standard right angles. Has social-media share features. I didn't even have to log in to repair and save my image! Criticism: the default "Save" was in GIF format. However, you can change the format by using the file tools (save as jpeg).

FotoFlexer
Great on-line image editor: I tried this and was able to do some nice, simple effects to fix a mediocre photo. It is less gimmicky than some of the other on-line tools and has some nice effects, such as "retro" and "cross process." It also has some standard portrait filters. Nice tool! I didn't have to set up an account or log in. The site gives you some options to share with Facebook, Flickr, PhotoBucket, and other sites.

Fotor
Not recommended unless with premium account, and I haven't tried that. Has decent tools and I used it a time or two with good results; however, they've started adding a big, fat watermark over the whole picture, and you can't get rid of it without going premium. When I was using it, I did have difficulty finding a brush or clone tool small enough to be useful--could not do detailed work with the big brush!
