Picnik is an online (Adobe Flash based) photo editor with Flickr integration.

I noticed it over on TechCrunch or Mashable yesterday and decided to give it a whirl. I'm often taking photos when I'm on holiday and uploading photos from a computer without Photoshop installed which means even cropping is impossible.

The beauty of Picnik is that I can upload photos to Flickr, open up Picnik, edit the photo and then save it back to Flickr. Okay, so it's no Photoshop but for basic photo editing it's great. I rarely do anything other than crop, edit saturation and modify contrast with a photo Picnik does all those things pretty well.

One thing to watch out for is that Flickr can detect which way you were holding your camera and then displays it the correct way on your photo page. When loading up one of these photos in Picnik this rotation doesn't happen. Obviously you then go and rotate the photo and save again but Flickr stills picks up the meta data saying the photo needs rotation. Basically just don't rotate your photos again in Picnik - Flickr will do this for you.
