If you want to perform standard edits, then you should try one of the free online programs like Picnik or Photobucket. You don’t need to create a profile with Picnik, but you do need to create a free online profile with Photobucket.
Both programs are very easy to use. Picnik is extremely useful for quick edits. On the main screen, you’ll see the Get started now button. Click on this button, and then upload your photo. This program can take a few minutes to upload your image so give it a few minutes.
Once the photo is uploaded, you’ll see buttons for Auto-fix, Crop, Resize, Exposure, etc. The Auto-fix button applies standard adjustments to your images, including fixing contrast, shadows and highlights. The program also has a Red-Eye button for correcting red eye issues.
After you apply simple edits to your photographs, click on the Create tab if you want to add items like clip art, effects or stickers. For example, in the Effects tab, you can select the Black and White filter, which converts your image into black and white. You can tweak the effect with the amount sliders for the Brush Size, Brush Hardness and Brush Strength.
Other filters include Matte, Vignette, Soften and Boost. You also have the option of adding touch up to images, including adding blush to a subject or fixing a blemish. While most of these effects are free, certain ones are only available if you upgrade to the premium version of Picnik.
Once you are done, click on the Save and Share tab. Here you can upload your image to Flickr, Twitter or Picasa. You can also save the image to your computer.
