/*############################################
Sample :
$thumb=new thumbnail("./shiegege.jpg");			// generate image_file, set filename to resize/resample
$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)
- If your GD not support 'ImageCopyResampled' function,
  change 'ImageCopyResampled' to 'ImageCopyResize'
