Images Optimize and Upload CF7


This is invaluable when working with non tech-savvy users who don't know how to reduce the sizes of images before uploading, and a big convenience for other users. I could wish the instructions were a little clearer, and the default values for a lot of the settings results in a very poor-quality image, so I would've chosen different, less strict limits for file size and quality settings. It's also not being updated to reflect the fact that it works with recent WordPress versions -- but it does, so far.



So: not a perfect plugin, but the only one I can find that does exactly what I need for image uploading on CF7.
