Thank you for your efforts. It does not work

Fantastic, little known gem
By , for WP 4.1

Even after using Smush.it and EWWW image optimizer on my media library, Prizm created massive savings.

I would agree that you should make sure you have a backup of files before running them through the Prizm API, but if you use these precautions then it is fantastic.

Would only add that the controls are all over the place so the UI/frontend could do with revamp. FYI, currently you need to go to Settings>Media to enter your API key.

Best in the market

Prizm image is the best plugin if you are worried about your image sizes. I am using this plugin for quit a while now and used this to optimize more than 20 sites. Awesome plugin!

Good Support and Updates

great plugin. Author keeps it updated and it really takes a load off of image serving.

Not impressed
By , for WP 3.9.1

Where do you enter the license number - it reads you enter it in media, but no place in my media to put it.
Then I have just read that for cloud you send them the license, so do you do the same for wordpress media ?

Deleted all the images on my site
By , for WP 3.8.3

Deleted all the original images on my site and replaced them with 2kb error messages. Thankfully I always have a backup.

Use with caution.

Faster page loads without quality loss
By , for WP 3.8

This is exactly what we were looking for. We love our high res images, but quality has always been a tradeoff with page load speeds. So far, this plugin has produced great looking images at a fraction of the size. Really happy about the impact it has had on our page load times.

Works well

The only issue i've seen is that it took a fair amount of time to do 25 images and didnt seem to finish, may be i should have waited longer though

Great but slow
By , for WP 3.8

I think it's a great alternative to other plugins that optimize your images. It could use some more settings and when you run the bulk opmization it's very slow and it takes forever.

That said the results are very good. I went from a Google Page speed of around 50 to aroung 90 just optmizing my images.
