[2.1] Theme preview missing in default theme after language change

[HendriXXX]

Hi!

I noticed that default theme preview, (user settings: Look & layout > Current theme), is missing when swithing language to Finnish.
In english preview thumbnail is shown like it should.

This issue is present when using RC2 and latest github version also..

I didn't find that file where that's configured.. can anybody help?

Thanks!

I found the reason.

I edited Settings.finnish.php by changing .gif to .png and now it works.. 

from

Code Select Expand

$txt['theme_thumbnail_href'] = $settings['images_url'] . '/thumbnail.gif';

to

Code Select Expand

$txt['theme_thumbnail_href'] = $settings['images_url'] . '/thumbnail.png';

Thanks for this.  Helpful.  We should probably check all of the language files for 2.1.
