Yes you are right :)
I changed this part of code in order to change the size of the first pic :)
<script language="javascript"><!--
document.write('<?php echo '<div class="tgh" style="background: none;"><a href="javascript:popupWindow(\\\'' . tep_href_link(FILENAME_POPUP_IMAGE, 'pID=' . $product_info['products_id']) . '\\\')">' . tep_image(DIR_WS_IMAGES . $product_info['products_image'], addslashes($product_info['products_name']), (MOPICS_RESTRICT_PARENT=='false'?'':250), (MOPICS_RESTRICT_PARENT=='false'?'':IMAGE_HEIGHT), 'hspace="5" vspace="5"') . '<br><img style="border: none;" border=0 src=images/zoom.gif></a></div>'; ?>');
//--></script>
But i forget to change the second restriction height :(
i changer the next IMAGE_HEIGHT to 250 too and it woeks good now :)
Thank you very much for the help :)
