title: Animated gif alternative with broad browser support?
body: <p>I would like to insert an animated image to a blog and a forum (hence I can't use javascript, CSS, SVG, HTML5 and other tricks), but the gif animation is too big, about 700K. It was made of a photo, so I can't reduce the colours below 256 palette entries, and the size of the image is also fixed to 350 pixel in height.
  I tried to convert it to "webp" animation with utility called "gif2webp", size reduced very much to 200K only. However it doesn't display in my favourite Opera browser. Than I tried "apng" format with utility "gif2apng", size was reduced again to 400K, but unfortunately the animation doesn't show up in Google Chrome Stable version. Is there any other alternative for a simple animation which can be inserted to a webpage as a simple image with the "img src=" HTML tag and which is supported by all major browsers?</p>
