Prizm is outstanding and when it was completely free without restrictions it was fantastic. For the money though at the mid level $49 it may for some be better value to us wp smush pro and then you get all the other extras that come with wpmu membership.

I get an error even on clean default wordpress installation with 2 pictures. I have an account with key and I've inserted it in 'media' options.

After 1-2min of site 'working something' I get 404 error I don't know what was happening because there was no progress bar, I do not know also what the 120sec means in ''How many seconds should we wait for a response from Prizm Image?'' Does this got something to do with ''max execution time''? What are server requirements and what configuration is needed for the plugin to run corectly etc etc. Please explain all this so I can re-review the plugin.

After having tried WP Smush, Compress JPEG & PNG images and EWWW Image Optimizer, I am totally convinced and impressed by the speed performance and the compression quality (however set at "Higher quality - Larger file size) of Prizm image 🙂 !! Try it is to adopt it 🙂 ! Well done ! Great work ! I really wish to thanks you for keeping that kind of tool free 🙂 !! Amicably, Pierre.
