I have just about completed my install of www.rayscountryham.com
I have a full page Hero Image above the header, and you will notice that the image is very slow to load.
Support assisted me with positioning this image and I am reluctant to change the size of the image (which is too large). I have resized the image in the image in the Media Library but cannot find a way to substitute it in Slider Revolution Slide 1: http://rayscountryham.com/wp-content/uploads/2017/07/Blue-Ridge-Mountains-186818265_5822x2848-e1499442866641.jpeg
In hopes of speeding the site, I installed W3 Total Cache, and it crashed my site, so I removed it.
I have now just installed Hummingbird plugin, and the site seems to be running OK, but I have not yet noticed any improvement in speed, especially with the Above the Header image.
Your suggestions for the above would be most appreciated.
BTW, hats off to Apex/Themeco for the extraordinary support during this install. It is why I purchased my third X Theme, and without which I could not have created just what I had in mind. Thank you and all for your support!
