Do you realize your resized images looks blur? This plugin fixing it. Sharpening resized jpg image uploads in your WordPress.
Works perfectly and without any configuration. I compared thumbnails of the same uploaded image before and after and there's a very significant difference.
I guess this is a bit new plugin but given the function of the plugin it could prove extremely useful to those like me whose business relies somewhat on the quality of the graphics on their sites.
PS. - In order for it to work on the images already in the database you may need to regenerate your thumbnails and Viola ! Sharp as tack images !
Plus...the developer provides a smooth response.
Good luck !
