Sorry it's taking me so long to get back here but in the middle of all this I got bronchitis. been sick for a few weeks.
I tried Optimizing All Photos, and it only did 3 of them. I guess the others were ok. Still the same thing. Slow and 2 minutes for saving, so I'm going down the path of trying the placeholder and the multiple sites to see which one works.
I'm also writing the site with html/css from scratch with Bootstrap which I use in work to see which method I like the best.
Thanks to all for your help.
