Forgot to add image related to the second part of the dicussion

Hello. 

"I am hoping to be able to include with my .jpg's/all photos with dimensions (height and width) visible in code." - You can try adding height and width to some images here.If this does not help, then you can try to insert images using the HTML code.But this is very inconvenient.

"Also when doing a page audit, I keep getting message that I need to serve an image with better resolution, image will show you the message. What is this mean?" - You need to add images to the program with exactly the same size with which they will be displayed on the site page.Now you have a picture with a size of 600 * 774, but it is displayed with a size of 300 * 387. First, reduce the picture to a size of 300 * 387, and then add it to the program.

You can do that with pictures in text objects, but cannot do that with pictures in image galleries.   So then if you use that in for the user experience (per Google) in text object, then you loose the lazy loading capabilities (defer imaging) in image galleries and you get dinged for that.

If I'm wrong please show me how to defer loading (L.I.) and have that good user experience that Google wants, ... please.

For lazy loading, I used Google PageSpeed Module.It was installed on my hosting. Perhaps there are other ways, but I do not know anything about them.

I kind of figured that might be the case.  My service provider has iis system.  I'll check into it more. Thank you.

Good luck to you.
