The last two updates you got weren’t that exciting, so we wanted to give you some more stuff to play with today. There are many improvements in the speed dial, but the first thing you might notice is that thumbnails are now generated differently.
Instead of always generating a thumbnail of the whole page, Opera intelligently tries to find a representative part of the site to display. To do that, it searches through all the images on the page and scores them based on size, position and file name. For example, an image called ‘logo.png’ in the top left corner will be a good candidate. Opera will make a thumbnail of the surroundings of that image, making it clearer which site is in the thumbnail.
Alternatively, it’s possible to specify exactly what your page’s thumbnail should look like. If your page knows how to handle the ‘minimized’ view mode, Opera will use that in the speed dial. If you don’t need a dynamically changing thumbnail, you can specify an image to use for your page by linking it in the page’s <head> like this (the image should be at least 114×114 pixels):
<link rel="image_src" type="image/jpeg" href="thumbnail.jpg">
Websites now also have the possibility to tell Opera how often they want their thumbnail updated. The Preview-refresh HTTP header can be used for this purpose. The example below will cause the thumbnail for this website to be refreshed every 10 seconds:
<meta http-equiv="preview-refresh" content="10">
Apart from all that goodness Opera now makes it easier for you to install plugins if you don’t have them installed on your system. And of course, there are all the bug fixes in this snapshot… I could talk about this for days :sherlock:. Check the full changelog for all the details.
