A long time I ago I "automated" the optimization of images on my site by running `optipng` in a cronjob. Every file that touches my server gets optimized.

I wrote about it here: https://ma.ttias.be/optimize-size-png-images-automatically-w...

Benefits:

- Don't have to think about it

- Optipng is really good at reducing PNG's to their bear minimum

Downsides:

- Doesn't resize images (if a 1024x768 is displayed as a 10x8, it'll still download the 1024x768)

- Only does PNG

- If your images are stored in git (and you didn't pre-optimize before committing/deploy), you can get merge conflicts

Still, better than nothing.
