YOU JUST DIG INTO “BLOG” >>> PAGE HEADER, UPLOAD THE IMAGE
THEN, STILL UNDER BLOG, THERE ARE TWO OTHER OPTIONS FOR ADJUSTING THE PAGE HEADER, JUST ZIGZAG THROUGH THEM, THEN, THE BIG IMAGE POPS OUT IN THE FRONT PAGE, BUT NOT IN OTHER PAGES.
IT WOULD BE NICE IF IT COULD BE THERE FOR THE WHOLE SITE.
PLEASE TRY THAT AND SEE IF THAT IS TRUE. MANY THANKS FOR YOUR GREAT WORK!
NB: THE PLUGIN I AM USING SHOWS A DIFFERENT INTERFACE FROM WHAT YOU USED IN THE TUTORIAL VIDEO, BUT THE FUNCTIONS ARE THE SAME.
