For some reason I could only find a few images from the scaled images issue that I was able to resolve. For the remaining images I can't find them on my wordpress (image gallery) and neither could I locate those in my Bluehost> cpanel> File manager.
I can't delete or optimize them if I can't find them! Bluehost, not surprisingly, has been no help at all.
Since I don't want to touch the .htaccess file (not a tech friendly person) I decided to try a cache plug-in instead to resolve the leverage browser caching issue.
Can a cache plug-in and and an image optimization plug-in help solve these issues?
