Image Thumbnail Creator

xavier039 · #1 (**permalink**) 03-04-07, 01:20 PM

I need a script that will resize images to 120x90 but of course I don't want it distorted. So what needs to happen is, once the image is resized and say its 140x90 the thumbnail will just be cropped to 120x90 get it? Can anybody help? I already have a script that resizes my images into thumbnails of 120x90 but they look awful. I'd rather have them resized and cropped if needed. Any help would be great.

Stating what scripting language you need this to be in would probably help along with any other requirements, such as doing this on the fly or saving the results to a file/database, for what type(s) of images...

It needs to be a php class. Here is my current php scripts that I am using. This is the upload_images.php

PHP Code:


			
 <?php

session_start();

include("include/config.php");

include("include/function.php");

include("thumb.class.php");

chk_member_login();

isMailVerified();



#echo "hello" . $_POST[action_upload];

#echo $config['audiodir'];

#echo $config['audiourl'];



if($_POST[action_upload]!="")

{

        if($_POST[field_myvideo_title]=="") $err="Upload: Please Provide an image title.";

        elseif($_POST[field_myvideo_descr]=="") $err="Upload: Please Provide an image description.";

        elseif($_POST[field_myvideo_keywords]=="") $err="Upload: Please provide tag/s.";

        //elseif(count($_POST[chlist])<1 || count($_POST[chlist])>3) $err="Upload: Please check (1 to 3) channel/s.";

        if($err=="")

        {

        STemplate::assign('secondpage',"second");

        //$listch=implode("|",$_POST[chlist]);

        //STemplate::assign('listch',$listch);

        }

}









if($_POST[upload_final]!="")

{

        #echo "uploading";

        if($_FILES['field_uploadfile']['tmp_name']=="") 

                $err="Please provide the image location.";

       

       

        if($err=="" && $_FILES['field_uploadfile']['tmp_name']!=""){

                $p=$_FILES['field_uploadfile']['name'];

                $pos=strrpos($p,".");

                $ph=strtolower(substr($p,$pos+1,strlen($p)-$pos));

                $im_size =  $_FILES['field_uploadfile']['size'];

                if( $ph!="jpg" && $ph!="png" && $ph!="bmp" && $ph!="gif")

                   $err="Invalid Format. The supported formats are png, jpg, bmp and gif";

                    $conn->execute($sql);

                    $vid=mysql_insert_id();

                    $vdoname=$vid.".".$ph;

        

        



        //VIDEO UPLOADING

        if($config['activexinstall']=="no")

        {

            }

        }

        //END

        $key=substr(md5($vid),11,20);

        $sql="update images set

                vdoname='$vdoname',

                vkey='$key' WHERE VID=$vid";

        $conn->execute($sql);

        

        thumb($config['AIMG_DIR'] . "/" . $vdoname, array(120,90));

        

        if(mysql_affected_rows()>=1)header("Location:$config[baseurl]/upload_success_images.php?viewkey=$key&upload=yes");exit;

        }

        

}





    STemplate::assign('err',$err);

    STemplate::assign('msg',$msg);

    STemplate::assign('head_bottom',"imageslinks.tpl");

    STemplate::display('head5.tpl');

    STemplate::display('err_msg.tpl');

    STemplate::display('upload_images.tpl');

?>

and this is the script that is currently being used to resize the images

Hopefully this helps out more. I am looking for a script that resizes my images similar to www.thatimagesite.com That site has very good thumbnails and they are both resized, cropped, and all 120x90.
