copyright in joomla 3x? Ant thumbnails problem

Hi
I found the copyright in index.php in template and managed to change it but I can't remove text "your Company"
How do I remove it?
And I also see that I have no control over the thumbnails size. They are small like 10 PX by 10 PX. I was trying to change it in the gallery module but whatever sizes I will put there it's stay as it is. Please see:

Help please.

Check template options for "Your company" text.

For thumb size add this to bottom of template_css.css:

#gallery img{
width:120px;
}

Hi Ivan
It does work but now thumbnails are blurred? How do I fix that?

Check width and height you have set in plugin settings. Locate plugin in plugin manager and enter it to see its settings
