Excluding Specific Photos

I’m afraid not. This is a blanket resizing tool which will resize all images (if required). We don’t intend this to be used to resize images for use in posts; WordPress provides better functionality for doing this through “add_image_size” function (search for it). This plugin should be used to prevent massive images being stored on the server – i.e. resize everything larger than 1200px-wide down to 1200, then use WordPress’ image functions to manipulate them depending on their position in the site.

Kind regards
