Missing gif file.

Hello,
Nice theme! There are a few little thingstaht bother me.

Since I installed the theme I get the following message in the log files.
Page not found : sites/all/themes/sib/images/bg-thead.gif
I looked into the directories but I couldn't find it. It's mentioned in the style.css file.

There are 2 themes shown in the themes list. Sib and Siberia. Siberia just allows you to install a few options and seems not to be a fully theme.

I'm using Drupal 5.2. Could you give me som emore information on these little problems?
Thanks.

With kind regards,

Sjaak Terwindt
