Couple of months before one of my friend was asking about Amazon S3 plugin for wordpress. For me most of them were either complicated or not working. So my main focus of the plugin was to be really simple and in the same time effective. I would say I have kind of achieved the goal to some extend in version 1.0 of this plugin release.
The toughest part in the plugin is to configure the Amazon S3 Setting, create a folder for caching and setup the wordpress cron file. Once these settings are done you don’t have to worry about anything else. The plugin will look for media files in your post and automatically schedule the files for amazon upload. Once the file is uploaded the media urls will be from the CDN. There are no changes done in your database and if you disable the plugin everything will go back to the old state.
