i tried find solution allow me convert/resize images (i tried find facebook solution), unfortunately had no luck or converter didn't work well. don't want restrict users size of images. means, users not need care if pictures have 5mb each or 200kb. files width size > 1200px converted width 1200, smaller sizes kept are. in addition, need thumbs not load images in full (1200px) size.
