Cкрипт за генериране на web thumbnails.

Трябва ми скрип на php или perl който да генерира
thumbnailsи на картинки качвани през ftp document roota на
web сървъра...Примерно...качил съм 2-3 gb снимки които искам
да се браузват през http но не ми се създава провию на всяка
от тези картинки че да го качвам и тн.Скрипта да може сам да
прави thumbnailsи при първото отваряне на картинката.
За сега намерих само един yappa който иска ImageMagic ама
той не работи както трябва...не иска да прави реглед на
картинката...
плс дайте някакви идеи...

Sample :
$thumb=new thumbnail("./shiegege.jpg"); // generate image_file, set filename to resize
$thumb->size_width(100); // set width for thumbnail, or
$thumb->size_height(300); // set height for thumbnail, or
$thumb->size_auto(200); // set the biggest width or height for thumbnail
$thumb->jpeg_quality(75); // [OPTIONAL] set quality for jpeg only (0 - 100) (worst - best), default = 75
$thumb->show(); // show your thumbnail
$thumb->save("./huhu.jpg"); // save your thumbnail to file
----------------------------------------------
Note :
- GD must Enabled
- Autodetect file extension (.jpg/jpeg, .png, .gif, .wbmp)
but some server can't generate .gif / .wbmp file types
- If your GD not support 'ImageCreateTrueColor' function,
change one line from 'ImageCreateTrueColor' to 'ImageCreate'
(the position in 'show' and 'save' function)
