When you upload an image through the PageFly image library and apply it to a section, simply click the "Optimize" button. The image will then be optimized according to the preferences set on the TinyIMG settings page.
If you've been working on your page for a while and want to optimize all images at once, simply click the TinyIMG logo in the PageFly file selector. This will automatically optimize all images using background processing.
You can monitor the image optimization process directly in the "Background Processes" section of PageFly.
Alternatively, you can also view the image optimization results directly in the TinyIMG "Image Optimization" section.
TinyIMG currently allows you to resize images to specified dimensions in the "Overview" tab on the Settings page.
