Try ipiccy. It is a editor very similar to picnik. One thing ipiccy features is a very nice ink/drawing tool you can use to draw a illustration from scratch or use it to edit your photos. Hope this helps!
If you're looking for more advanced editing tools try Gimp, its a free download at gimp.org. Its a cross program editing suite that runs on windows,mac,and linux systems, that has most of the capabilities of photoshop for FREE. I use it all the time and it has a great user forum community.
Picnik.com is a really good site, but it is closing down soon. I believe that it is going to stay open for Google+ though. I personally use lunapic.com a lot. It has a large variety of fonts and animations to choose from. If you are looking for something simple, photobucket.com and pizap.com have good editors also.
I often use the Aviosoft video converter is all-in-one video converter that converts all video formats including DVD movies and HD videos It can convert all videos to play them on PC, portable media players! Using Aviosoft video converter you can finish video conversion, video editing, video download, iPhone ringtone creation, pictures slideshow etc. in one program.
