Out of curiosity, why don’t all these blog posts from affiliate sites, hosting companies, theme developers, AdSense sites, plugin owners (or anywhere else) ever grow some gumption and say _(something like)_ : “STOP UPLOADING BIG ASS IMAGES IN THE FIRST PLACE!!!”
I can’t quite say I’ve ever seen a post resembling that much truthful bluntness. So, perhaps I can add a bit of gentle rhetoric around that message while still maintaining the importance of the above text in red. Here goes.
Use a FIXED WIDTH – NOT FLUID
Every WordPress Theme is unique. Some themes have an option of fixed or fluid width. Fluid width, flexible width, or full screen width might be additional terms to use – but the result is the same. On any screen possible, the theme is designed to take up as much room as possible.
That would also be known as incredibly impossible, not possible, no way in the world, not actually going to really happen, for your own sake please stop thinking that it looks cool in-your-own perspective.
As someone told me years ago, “This is Business: Unless Y-O-U can print your own money, your own opinion does NOT mean jack sh!t. Never forsake that
