It doesn’t make the graphic open faster with the width and height are there, but what it does is open the post with the size built in, so that anything that follows stays put. Without the width and height specified in the graphic, when the post opens the first time, you get that tiny little box where the graphic will be - if it is HUGE (and we don’t know until it fully opens) and we are trying to read something after that graphic starts opening, we keep losing our place as it opens to the full size. If it’s a really small one in both physical size AND in bytes, it’s not a problem, but the big ones are. :(
The “crawl” up the page syndrome. There is one poster on FR that posts a lot of big byte pictures all in one post and trying read the rest of the page is impossible until it loads..even on cable it’s a pain..They do great posts but need a byte reducer and number of pictures in one post reducer big time!.
