Need to correct colors, remove red-eye, or change the format of an image? Don't want to shell out hundreds of dollars for Adobe PhotoShop? ImageAnalyzer is freeware, and light, and it does many functions that the big apps do.
I tested the automatic color correction in ImageAnalyzer, and it worked pretty well--though I still preferred the Levels function in Photoshop for fine-tuning. There's a big difference between the price of the free ImageAnalyzer and the many hundreds that PhotoShop costs, though--and for quick-and-dirty correction of a scanned photo or document, ImageAnalyzer works wonders.
Resizing is easy and quick, but I wish ImageAnalyzer had an option to change the DPI of an image. For example, someone wanting to modify a scanned image for the Web would change from 300 to 72 dpi while they're resizing it. You can't do that with ImageAnalyzer. This seems like a particularly glaring omission. Forum posts suggest the app author feels DPI is meaningless in a practical context and image size is all that matters. DPI is important for those printing physical books or merchandise, to use two examples, so it would still be nice to have the option.
There's a batch-processing plugin for ImageAnalyzer on the vendor's Web site, for performing tasks on a large number of images, but this particular plugin is donationware. Send Meesoft some money and grab this, and ImageAnalyzer becomes even more useful--and Photoshop becomes even more unnecessary for the bulk of your image processing work.
Other than the lack of DPI adjusting, ImageAnalyzer has a ton of functionality for a free product. Since it takes up so little memory and CPU, consider using it in place of Photoshop when RAM or CPU usage is a concern. Or, if you can't afford Photoshop, ImageAnalyzer will do the trick for many important image manipulation tasks.
