I found a post from this forum that explains very simply about how to resize images within WordPress’ own resizing method or using the “Smush it” plugin.
I just tested the Smus it yesterday and it works great!
My question is however that should I resize the pictures BEFORE uploading to WordPress or is it just as good to resize them with WordPress’ own functionality or Smush it?
I don’t mean the caching of images but the actual size in pixels.
I ask this because I have read earlier from a quite recognized blog (which I don’t remember now) that it could slow down the site if you use plugins to resize the images.
A picture is at the WordPress library for example 600×600 pixels and then there would be a plugin that would resize the image to for example 300×300 pixels but it would actually have to resize it every time a quest enters the website instead of the picture “truely being” size of 300x300pixels.
And this could slow down the site?
Any opinions on this one?
