1. Open index.php
Delete before </div> <!-- selector --> :
<? if ($cut_url==true && $cut_url_user==true) { ?><div id="preferencias"<? if (isset($lang)) { echo ' class="'.$lang.'"'; } ?>><a id="pclosed"><span><?=TXT_PREFERENCES;?></span></a><a id="popen" style="display:none;"><span><?=TXT_PREFERENCES;?></span></a></div><? } ?>Delete after </div> <!-- selector --> :
<form id="form_up" enctype="multipart/form-data" action="<?=PATH_SCRIPT;?>" method="post">
<? if ($cut_url==true && $cut_url_user==true) { ?>
<div id="pref-panel" style="display: none;"><div id="cajon-pref"><p id="prefurl"><input name="" type="checkbox" id="cortarurl" value="" <? if(isset($_COOKIE['prefurl'])) { ?>checked="checked"<? } ?> /><label for="cortarurl"> <?=TXT_TINYURL;?></label></p><div id="save"><a id="savepref" /><?=TXT_CLOSE_PREF;?></a></div></div></div>
<? } ?>
In engine.php delete :
And
// Short URL using services like TinyURL.com
function cortar_url($url) {
global $tiny_api;
$tiny = $tiny_api.$url;
$chtny = curl_init();
curl_setopt($chtny, CURLOPT_URL, $tiny);
curl_setopt($chtny, CURLOPT_RETURNTRANSFER, 1);
$ShortURL = curl_exec($chtny);
curl_close($chtny);
return $ShortURL;
}
// SI esta habilitado cortar url.. hagamolo.
if ($cut_url==true) {
// Si se da a elegir al usuario, cortemos si el quiere.
if ($cut_url_user==true) {
// El usuario quiere cortar url...
if (isset($_COOKIE['prefurl'])) {
$ShortURL = cortar_url($URLimg);
}
// Cortamos si o si ya que la prefencia es de script y no de usuario.
} else {
$ShortURL = cortar_url($URLimg);
}
}
2. For resize buttons, in index.php delete :
<div id="redimensionar">
<div id="redimensionar_cajatitulo">
<div id="redimensionar_titulo">
<div id="boton_redimensionar"<? if (isset($lang)) { echo ' class="'.$lang.'"'; } ?>><span><a id="rclosed"></a><a id="ropen" style="display: none;"></a></span></div>
<div id="red_mensaje"><span id="red1"><?=RESIZE_DSC;?></span><span id="red2" style="display: none;"></span></div>
</div>
</div>
<div id="redimensionar-borde" style="display: none;">
<div id="cajonred">
<div id="ancho_deseado"><?=RESIZE_WIDTH;?> <span><?=RESIZE_PIXELS;?></span></div>
<input name="resize" id="resize"/>
<div id="kepp"><?=RESIZE_KEEP;?></div>
</div>
</div>
</div>
For engine.php remove, there is too many lines, ask Rodolfo for this
