Introduction
CW Image Optimizer Plugin reduces image file size and improve performance using Linux image optimization programs. This will automatically and without any loss optimize the images as we upload them to your blog. It can also optimize the images that have already uploaded in the past. Because CW Image Optimizer uses lossless optimization techniques, your image quality will be exactly the same before and after the optimization. The only thing that will change is your file size.
Uses of CW Image Optimizer

happy, and can increase the revenue from advertisements.2. Faster backups. Smaller image sizes also fastens the backups.
3. Less bandwidth usage. Optimizing images can save hundreds of KB per image, which means significantly

process, and return the images. One can optimize hundreds of images in just a few minutes.
