Description Pat David 2018-08-28 14:59:47 UTC 
Gilles,

The carousel images are all .PNG files.  This is awesome for quality.  Not so awesome for file size... :(

Loading the front page requires 13.2MB of download (almost 2 minutes to load over fast 3G)!

I would like to:

1. Compress these to JPG (trying to keep as much visual quality as possible while keeping the file sizes smaller).
2. Consider reducing the number of images in the carousel to cut down on total download size.

Can I go ahead and compress the carousel images?

You are right.

Using JPEG will reduce bandwidth. Let's go to convert PNG to JPEG with imagemagick...

    Compress carousel images from PNG to JPG

    This also removes the /static/img/carousel/info.txt file as it is
    no longer needed (use /data/carousel.yml intead).
