How did you upload the pics (batch upload or single)?
When you download the fullsize pics via ftp, can you open them correctly?
It's in German - here are some translations
'inactive_tab' => '<td><img src="images/spacer.gif" width="1" height="1" alt="" /></td>'."n".'<td align="center" valign="middle" class="foot"><a href="{LINK}"><b>%d</b></a></td>'."n"
if (($approved == 'YES') && is_object($xoopsUser)) $xoopsUser->incrementPost();
