PHP je můj koníček 
Kód:
<?php
class ImageException extends Exception {
public function __construct ()
{
print "Nedovolený formát souboru!";
}
}
class Image {

}
public function unlinkTmpImage ()
{
if ( is_string ( $this -> ImageName ) )
{
return ( unlink ( $this -> Directory . $this -> ImageName ) );
}
}
}
?>
Edit:
Použítí je následující
Kód:
//upload na server //delej nejakou podminku na is_uploaded_file
move_uploaded_file($_FILES['newImage']['tmp_name'],$_SERVER['DOCUMENT_ROOT']."/path/".$tmp );
//nová instance nastavi jmeno a cestu
$imh = new Image( $tmp, $_SERVER['DOCUMENT_ROOT']."/path" );
//zjisti udaje o obrazku preda objekt Image_Statement a tam zkontroluje
$proper = $imh -> getProperties ();
//nstaveni jmen obrazku a prilozeni typu (gif, jpeg, png)
$nameB = $tmp."B.".$imh -> Type;
$nameS = $tmp."S.".$imh -> Type;
//udela obrazek o veliksoti 320x220 a mensi 114x87
$big = $proper -> copyImage ( $nameB ) -> resampledImage ( 320, 220);
$small = $proper -> copyImage ( $nameS ) -> resampledImage ( 114, 87);
//zrusi tmp nahravanej obrazek kvuli velikosti
$destroyTmp = $proper -> unlinkTmpImage ();
Trida je udelana jako mala FAKTORY predavam objekt z class Image do Image_Statement
huh
Edit2:
ve windowsech staci povolit jen tu knihovnu gd2.dll v php.ini a reset apache
v linuxu je myslim podpora gifu a png, ale jpeg musis mit zvlast zkompilovanej
tot asi vsechno
[JavaScript] nefunkcni zvetsovani obrazku v FF (uvozovky)
Moc prosim o radu.
