Do I need graphics optimization

Question

Image optimization

Hello. I want something strange, maybe someone can point me in the right direction.
You need to check static pages for unoptimized graphics. For example, it's good if a large picture has a size of 80kb, but not a picture of 20x20px.

Answer 1

There is an extension for FireFox - YSlow. Embedded in FireBug and shows convenient statistics on the page, displays a list of possible optimizations. Using this information, you can check unoptimized graphics, and not only it.

Answer 2

You can, for example, use wget to download images from a page, then use ImageMagic's utilities to get information on these images (identify).
If the site is yours, you can do the same with auto-optimization - we go through all the directories in search of images, get information using identify and, if necessary, use some kind of convert to optimize.
