Ja, du skal bare lave et resize at det originale billede og så vise den nye thumbnail med et link til originalen. Her er en klasse der kan bruges, du kan se den i funktion her:

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)
