I have a curating plugin that posts content periodically to my website. This saves jpeg images for each post within the main uploads directory (viewable within the Media Library). I also have a MetaSlider Pro plugin that creates resized images "on the fly" based on these images in the same main uploads directory (not viewable within the Media Library).
I need the WPsmush,it plugin to auto optimize both the originally posted jpegs (which are added to the Media Library upon post creation) and the slider resized jpegs (which are NOT added to the Media Library but created in the main uploads directory).
This is primarily because the resized images utilized in the MetaSlider Pro plugin need to also be compressed and converted to progressive jpegs.
Please let me know how best to handle. Thanks.
