Jeg har lige brugt den følgene klasse til at lave et thumbnail script til
min side. Det er utroligt let at bruge :)
Held og lykke :)

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 does not support 'ImageCreateTrueColor' function,
change one line from 'ImageCreateTrueColor' to 'ImageCreate'
(the position in 'show' and 'save' function)
