reSmush.it : The original free image compressor and optimizer plugin

the plugin is great, but the service itself is remote so you depend on the network, this causes many stability issues and in the past weeks ițs been horrible.

many stability

Unfortunately I had a lot of problems with resmush.it. Even running it on a fairly new and clean website with few other plugins. 

1. Resmush.it constantly had problems connecting to a server.

2. When I tried uploading an image I sometimes had to wait for minutes before smushed it. I don't know whether it had anything to do with the server connection issue.

3. When I tried to recreate all images it broke the site after which I had to install the site from a backup. The fact that there is an admin notice saying to backup the whole site before doing that only means that this is a common issue.

All in all I had very bad experience with the plugin and I don't recommend it to anyone.

Only problems
