Themes preview in siteoptions
Another little new feature mainly done by Benjamin: Little preview images for the theme selector in Site Options. To see it in action, just login into your Freeflux account (or update your local installation), go to site options and change a theme. Tataa :) You can also hover over the thumbnail and see a larger version. No more saving the theme just to see how the page will look like.
Of course, if you change your CSS or XSLT on a standard template, the preview images are not accurate anymore, as they are not rendered live.
If you do your own themes and want to have a preview picture as well, just make a "preview" folder on your themes folder and name the jpg like the css, but replace .css with .jpg, eg.
/themes/mytheme/css/main_foo.css
will become
/themes/mytheme/preview/main_foo.jpg
And make the preview picture approx. 400x240 pixels large.
