I am a novice and learned the hard way.
Had a long learning curve over the weekend regarding site speed and image specs. And I have written this below for anybody who comes across the same basic site speed problems and retina ready images. I have however also got a home page problem that I actually need the help with hence the post. So please be patient.
I now know that
Worpress, themes and plugins can and do create various size images from your original image in the background that are stored on your server. You have some control over this in settings for wordpress and in my case woocommerce.
You do not have access to the additional images through wordpress in the normal way, you have to be explicit with urls calling the different size image directly instead of the image library.
X Pro theme does not use SRCset but other plugins do like Woocommerce.
WP Retina 2x plugin simply saves the standard worpress and plugin resized images at 2 x their original size and labels them so, i.e “some_image_100x100.jpg” (100x100px thumbnail) is now saved at 200x200px and labeled "email@example.com. it does this for all registered sizes of images on your site. This means if you run the retina plugin, you will have 2 x the total number of images that you had before excluding your original upload (if you have decided you need retina images for everything). So you are doubling your images at twice the size .
X pro has their own way of keeping the site responsive and retina ready but it is based on re scaling and not applying a “correct” sized image so the size overhead will still be there for site speed and loading.
You can use a piece of code to re enable SRCset if you wish but that is at the detriment of how x, pro works under the hood and may have effects that have not been considered. There are other posts on this forum for that. Themeco please fill in any missing blanks for me
Having got that off my chest and hopefully being of help to someone else as I found this information splintered across forums, here’s the bit I need help with.
My original resent revamp of the home page is fairly image heavy, so I have set about re evaluating individual images and sizes based on their use an implementing this. The editor or me threw a wobbly last night and I chose NOT to save the work.
However it appears the information is there but corrupted as I can see it (after a fashion) directly in wordpress editor but Pro editor is showing that I have no content or sections existing at all.
Can you help me with this please. ( I have reverted the site to the old back up home page so the site is ok) So please follow the url below:-

I cannot see how to retreive the page. Any help gratefully received as always.
