One of the most common questions I get when I’m training people is “How do I resize photos so I upload them to WordPress (or Typepad)?” I just found a free online photo editor that I will recommend to my clients from now on. It’s called Picnik, and their free suite of tools is powerful enough to resize photos by percentage (which is my preferred method), crop and rotate them, and do red-eye reduction and color adjustments. You just upload your photo and work within Picnik’s cool interface. You can also upgrade to the premium version in order to be able to save photos, get more special effects, and have an ad-free photo editing experience.
This tool is also completely web-based, which means it works with any operating system. Try Picnik and have fun with your photos!
