some startup performance savings in fewer http requests to fetch the image. small for sure but it's something?

If I had to guess, it's because it's loading a bajillion images that are not compressed

This site loads very slowly, most images are in the megabyte range :(

I'd recommend using lower resolution inline images on your pages... they're very slow to download.

Maybe browsers should have a mode where they don’t display images that are larger than X bytes if you don’t click on them

Impressed by the loading speed of pictures, how does that work?

Hello we reduced the size of the images. Is the page loading faster now?

codezero • Jul 9, 2014 • View on HN

The page loads fast but the images are crawling, they really need to get these things on to a CDN or scale them down to the size they are displayed at (the file size of one of these things that I checked is 2 megabytes, and the server is transferring at 50KB/s or less)

The images load very slowly. Perhaps you could downsize them a little? The first one I clicked on was 3283x2015 pixels, way too large for something that occupies maybe a quarter of my screen.

The page renders really laggy for me. Seems like it'd benefit from dynamically loading in the images, or at least user more compression on the images. Also, the images have been shrunken to fit the page. They should just be that smaller size to begin with; you could probably get the page down to 8MB with minimal loss.
