Is there any plugin that will automatically compress JPG images similar to Photoshop's "Save for Web and Devices" function?
I've tried the "Smush It" plugin but one image I tried with this was 114kb and "Smush It" reduced it to 112kb.
However, with Photoshop, I can reduce this to just 32kb using the "Medium" setting, or 66kb with "High". I don't really want to go through all the images (there are tons!) and download each one, optimise it this way and re-upload it - besides, I also want the thumbnails which WordPress automatically generates to be compressed like this.
Is there anything out there that can do this?
