Hey!
Thanks for you quick responses. @the.rampage.rado I'm not using ImageMagic.
@datakick Tried to update to latest bleeding edge, same issue. When i generate thumbnails, they are generated as both jpg and webp, where the webp is significantly smaller. However when i try to do the same thing for the homeslider, the images are the exact same size. This is how I call ImageManager:Resize method
ImageManager::resize($sourceFile, $filepathWebp, null, null, 'webp') - where the sourceFile is a jpg file, the filepath is specified with a wepb extension...any ideas?
