    <?php class redimensionar{ var $image; var $image_type; function load($filename){ $image_info = getimagesize($filename); $this->image_type = $image_info[2]; if($this->image_type == IMAGETYPE_JPEG){ $this->image = imagecreatefromjpeg($filename); } elseif($this->image_type == IMAGETYPE_GIF){ $this->image = imagecreatefromgif($filename); } elseif($this->image_type == IMAGETYPE_PNG){ $this->image = imagecreatefrompng($filename); } } function save($filename, $image_type=IMAGETYPE_JPEG, $compression=75, $permissions=null){ if($image_type == IMAGETYPE_JPEG){ imagejpeg($this->image,$filename,$compression); } elseif($image_type == IMAGETYPE_GIF){ imagegif($this->image,$filename); } elseif($image_type == IMAGETYPE_PNG){ imagepng($this->image,$filename); } if($permissions != null){ chmod($filename,$permissions); } } function output($image_type=IMAGETYPE_JPEG){ if($image_type == IMAGETYPE_JPEG){ imagejpeg($this->image); } elseif($image_type == IMAGETYPE_GIF){ imagegif($this->image); } elseif($image_type == IMAGETYPE_PNG){ imagepng($this->image); } } function getWidth(){ return imagesx($this->image); } function getHeight(){ return imagesy($this->image); } function resizeToScale($width){ $width=800; $height=800; if($this->getWidth()>$width || $this->getHeight()>$height){ if($this->getWidth()>$this->getHeight()){ $height=($width * $this->getHeight())/$this->getWidth(); $this->resize($width,$height); } elseif($this->getHeight()>$this->getWidth()){ $width=($height * $this->getWidth())/$this->getHeight(); $this->resize($width,$height); } else{ $width=$this->getWidth()/($this->getWidth()/$width); $height=$this->getHeight()/($this->getHeight()/$height); $this->resize($width,$height); } } else{ $width=$this->getWidth(); $height=$this->getHeight(); $this->resize($width,$height); } } function resize($width,$height){ $new_image = imagecreatetruecolor($width,$height); imagecopyresampled($new_image, $this->image, 0, 0, 0, 0, $width, $height, $this->getWidth(), $this->getHeight()); $this->image = $new_image; } } ?> if(move_uploaded_file($tmp_name, $uploadfile)){ include_once('redimensiona.php'); $image = new redimensionar(); $image->load($uploadfile); $image->resizeToScale(800); $image->save($uploadfile); ta aí funciona beleza ...

    deu certo agora se a foto for menor deixa como esta ficou assim <?php function redimensionar($imagem, $name, $medida, $pasta){ $img = imagecreatefromjpeg($imagem['tmp_name']); $x = imagesx($img); $y = imagesy($img); $medida[0]=800; $medida[1]=800; if($x>$medida[0] || $y>$medida[1]){ if($x>$y){ $medida[1]=($medida[0] * $y)/$x; } elseif($y>$x){ $medida[0]=($medida[1] * $x)/$y; } else{ $medida[0]=$x/($x/$medida[0]); $medida[1]=$y/($y/$medida[1]); } } else{ $medida[0]=$x; $medida[1]=$y; } $nova = imagecreatetruecolor($medida[0],$medida[1]); imagecopyresampled($nova, $img, 0, 0, 0, 0, $medida[0], $medida[1], imagesx($img), imagesy($img)); imagejpeg($nova, "$pasta/$name"); imagedestroy($img); imagedestroy($nova); return $name; } ?> <?php if(isset($_POST['acao']) && $_POST['acao'] == 'cadastrar'){ $foto = $_FILES['foto']; if($foto['type'] == 'image/jpeg'){ require("resize.php"); $name = 'foto='.md5(uniqid(rand(), true)).".jpg"; redimensionar($foto, $name, $medida, "fotos"); } } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>Redimensionar Imagem</title> </head> <body> <form method="post" action="" enctype="multipart/form-data"> <font face="verdana" color="#888888" size="2">Fotos</font><br /> <input type="file" name="foto" /><br /><br /> <input type="submit" value="enviar fotos" /> <input type="hidden" name="acao" value="cadastrar" /> </form> </body> </html> mas agora precisava implementar ele nesse código como disse acima <?php if(isset($_POST['submit'])){ $id_noticias = $_GET["id_noticias"]; $fotos = $_FILES["img"]; $pasta = 'fotos/'; foreach($_FILES["img"]["error"] as $key => $error){ if($error == UPLOAD_ERR_OK){ $tmp_name = $_FILES["img"]["tmp_name"][$key]; $ext = array("jpeg","jpg","png","gif"); $fotos = md5(uniqid(time())) .

    Tiago Biage , esse código aí funciona beleza e é bastante util ,,mas para esse meu código não serve pois também quero evitar fotos grandes no servidor , mas esse teu código vai me ser util em outro projeto,, uma pergunta tipo ali testei e vi que ele faz a proporção corretamente ,,mas teria como tipo fazer outro valor para ele diferenciar em qual parte tem a medida maior?? ex foto tem a largura maior que a altura então ficaria 800 com a altura proporcional certo <img src="thumb_maker.php?img=ENDERECOIMAGEM&outrovalor=800" border="0"> ex foto tem a altura maior que a largura então ficaria 800 com a largura proporcional certo <img src="thumb_maker.php?img=ENDERECOIMAGEM&outrovalor=800" border="0"> agora se os valores da imagem forem menor que 800 mostra o tamanho real. vlw cara mesmo assim,,,,

    Olá consegui desenvolver um código pegando um pouco aqui e ali que faz redimenciona a imagem igual no orkut exe: se Horizontal for maior que 800 ele faz o resize para 800 proporcionamente com o tamanho verticcal então fica +- assim 1280 x 800 = 800 x 533 +- isso .. e o legal que faz extamento o mesmo se de em vez de horizontal a vertical for maior assim: 800 X 1280 = 533 x 800 mas tem alguns erros que não consegui corrigir segue o código resize.php <?php function redimensionar($imagem, $name, $medida, $pasta){ $img = imagecreatefromjpeg($imagem['tmp_name']); $x = imagesx($img); $y = imagesy($img); if($x>$y){ $medida[0]=800; $medida[1]=($medida[0] * $y)/$x; } else{ $medida[1]=800; $medida[0]=($medida[1] * $x)/$y; } $nova = imagecreatetruecolor($medida[0],$medida[1]); imagecopyresampled($nova, $img, 0, 0, 0, 0, $medida[0], $medida[1],imagesx($img), imagesy($img)); imagejpeg($nova, "$pasta/$name"); imagedestroy($img); imagedestroy($nova); return $name; } ?> quero implementar ele nesse código de mullti envio <?php if(isset($_POST['submit'])){ $id_noticias = $_GET["id_noticias"]; $fotos = $_FILES["img"]; $pasta = 'fotos/'; foreach($_FILES["img"]["error"] as $key => $error){ if($error == UPLOAD_ERR_OK){ $tmp_name = $_FILES["img"]["tmp_name"][$key]; $ext = array("jpeg","jpg","png","gif"); $fotos = md5(uniqid(time())) . "." . $ext[1]; $uploadfile = $pasta . basename($fotos); if(move_uploaded_file($tmp_name, $uploadfile)){ echo "<script>alert('Publicado com Sucesso!');document.location.href='java script:history.back()';</script>"; $insert = mysql_query("INSERT INTO fotos (id_noticias, fotos) VALUES ('$id_noticias', '$fotos')"); } else{ echo "<script>alert('Erro ao Publicar!');document.location.href='java script:history.back()';</script>"; } } } } ?> o erro no resize é que se foto for menor que 800 ele faz ela ficar com 800 se 10 po 10 ele faz ficar com 800 por 800 tenso isso rsr quem puder ajudar vlw.
