When articles and images are copied, it increases the site’s server load.
While that is technically accurate, the difference isn’t as clear cut.
Images take server space to be stored and bandwidth to be served. If you aren’t using your own, you’re using someone else’s, and some folks aren’t as kind in response to that as others.
Some don’t care, others can get you banned from your hosting provider, and some might even ensure that the remotely served images on your site are not at all what you intended (imagine every remotely served image on your site suddenly replaced with porn, for example).
But, before you upload someone else’s image to your server, make sure that you have their expressed written permission or that at least the image is available under a license that lets you do so (and that you comply with that license). Otherwise, you run the risk of crossing far more dangerous legal waters: https://www.copyright.gov/dmca/
images in the library when many posts increase wp source.
I’m not sure what you mean by “increase WP source,” but if you mean it affects how your site loads, that is factually inaccurate. The amount of images stored in your WordPress Media Library does not affect how your site loads.
So what should I do to thoroughly optimize the images on my site?
We have some general recommendations at https://projectdmc.org/documentation/article/optimization/
I recommend doing the following to optimize your website images:
- Decrease image size using tinypng.com
- Use WebP format using https://projectdmc.org/plugins/webp-converter-for-media/
- Get a CDN provider
