Change
'xoops_imageurl' => XOOPS_THEME_URL.'/'.$xoopsConfig['theme_set'].'/'
to
'xoops_imageurl' => 'http://www.yourdomain.com/pathtoimages/'
But as before mentionend, if you want to change the theme the path to the images will be wrong.
'xoops_imageurl' => XOOPS_THEME_URL.'/'.$xoopsConfig['theme_set'].'/'
'xoops_imageurl' => 'http://www.yourdomain.com/pathtoimages/'
$xoopsTpl->('modulecomment1', '<!-- generated from script script-name in line xyz to be displayed in template template-name //-->');
