Preparing photos for Flickr
Before uploading I do some quick adjustments in Photoshop. I add a Shadow/Highlight adjustment (Image>Adjustments>Shadow/Highlight) or a Levels adjustment (Layer>New Adjustment Layer>Levels) to those photos that need lightening or added contrast. Then I run the Image Processor that's built into Photoshop CS2 (File>Scripts>Image Processor) to quickly resize the photos to fit in a 400x400 pixel space, saving them as jpegs to a new folder. Then I upload the entire folder of fixed images using the Flickr uploader. It's a cinch.
