Reply To: Looking for WP technical help!
Bruce,
WordPress automatically creates and stores different sized files when you upload your images. That’s why you have the option for different sizes when you import your image into your post (full size, thumbnail, medium).
I’m not sure if it stores the resized image when you use code or if it just resizes “on the fly” as the images load.
I would guess the latter, because I think this is the same process it uses to resize featured images on posts and pages. I’d need to dig to find out for sure, though.
Either way, if it’s smaller, it’s smaller, in terms of bandwidth. That’s how I understand it.
