Testing Compressive Images (compressive-test)

A series of pages to test compressive images. Based on the conversation started by Jason Grigsby (@grigs) here: http://lists.w3.org/Archives/Public/public-respimg/2013Sep/0015.html

These are a series of test and control pages, each with progressively more images.

Original Images

I was looking for a wide variety of images and stumbled on the National Geographic wallpapers (http://photography.nationalgeographic.com/photography/wallpapers/). These images are 1600 X 1200 and total around 11M.

Control Images

The control pages have images which are 500 X 375 saved with a compression level of 12 from the Photoshop Image Processor script. They come in with a total weight of 6.4M.

Test Images

The test pages have images which are 1600 X 1200 saved with a compression level of 0 from the Photoshop Image Processor script. They come in with a total weight of 4.4M.

File Names

The HTML files are named to indicate the number of images on each page as well as whether they are a test or control page.

5 Images

  • 005-test.html
  • 005-control.html

10 Images

  • 010-test.html
  • 010-control.html

15 Images

  • 015-test.html
  • 015-control.html

...and so on.

More could certainly be added, but until we’ve done some initial testing we won’t know the best way to structure/instrument these.
