GT metrix - Use a CDN error for 7 images

HI there,

I’m getting the error " please use a CDN " on Gt Metrix for https://www.synctherapy.ca/ and I’m not sure how to fix it.

I believe it’s new since I just changed from Bluehost to Siteground but can’t give 100% confirmation for that. It’s for 7 of my images.

Do I have to reupload them? Should I ignore it?

Open to any suggestions for improvements on my site as well if you come across something.

Pretty new to all of the website stuff but competent enough to understand most things
