how to add image-border around an image?

Is there any simple way to add a image border around an image?

Reason is I want to create a drop-shadow effect around the image.

The images are loaded as thumbnails and are 110x75 px... Im thinking about creating a shadow border, but dont know how to add this to around the image, anybody 开发者_开发问答know a way?

PHP preferrably...

You can use the GD library or ImageMagick to alter the actual image in PHP, but you can also achieve a similar effect in CSS, if it is only required on a web page.

There is a complete tutorial on doing it with PHP and GD here:

function addBorderpng($add){
    $border=5; 
    $im=imagecreatefrompng($add);
    $width=imagesx($im);
    $height=imagesy($im);       
    $img_adj_width=$width+(2*$border);
    $img_adj_height=$height+(2*$border);
    $newimage=imagecreatetruecolor($img_adj_width,$img_adj_height);     

    $border_color = imagecolorallocate($newimage, 255, 255, 255);
    imagefilledrectangle($newimage,0,0,$img_adj_width, $img_adj_height,$border_color);

    imagecopyresized($newimage,$im,$border,$border,0,0,
    $width,$height,$width,$height); 
    imagepng($newimage,$add,9);  
    chmod("$add",0666);

}

add Border around an Image by php GD

<?php

$img_src = '3.jpg';

$img = imagecreatefromjpeg($img_src);
$color = imagecolorallocate($img, 132, 15, 153);
$borderThickness = 10;

drawBorder($img, $color, $borderThickness);


    function drawBorder(&$img, &$color, $thickness)
    {
        $x1 = 0;
        $y1 = 0;
        $x2 = imagesx($img) - 1;
        $y2 = imagesy($img) - 1;

        for($i = 0; $i < $thickness; $i++)
        {

            imagerectangle($img, $x1++, $y1++, $x2--, $y2--, $color);
        }

    }

header('Content-type: image/jpeg');
imagejpeg($img);
?>

and Add Borer to an Image using CSS

.border
{
    width: 100px;
    height: 75px;
    border : 3px solid rgb(132, 15, 153);
}
<img src='3.jpg' class='border'>

You would need to use CSS to create this effect. There are several options.

 .img{
      border-top:none;
      border-left:none;
      border-right:solid 2px #dddddd;
      border-bottom:solid 2px #dddddd;
 }

is the simplest but it does not look so great.

To make even better shadows you can use a plugin for jQuery such as the shadows plugin. It creates nice drop shadow effects on any element on the page.

If this is just visual sprinkles you could try the CSS3 box-shadow property. It will only work on Firefox, Safari and Chrome though, so it's a only a "progressive enhancement". This tutorial should help.

Alternatively you can use this CSS for a basic effect. gallery is whatever class name you give to the element surrounding the images (i.e. via <div class="gallery">...</div>). Width/height are optional, but if the images are all the same size then it's better to use CSS instead of the width/height attributes on the images themselves.

.gallery img {
    width: 100px;
    height: 75px;
    border-width: 0 3px 3px 0;
    border-style: solid;
    border-color: #ccc;
}

Better solution:

function addBorderpng($add,$bdr=1,$color='#000000'){
    $arr = explode('.', $add);
    $extension = strtolower(end($arr));
    $border=$bdr;
    if($extension == 'jpg'){
        $im=imagecreatefromjpeg($add);
    }
    else if($extension =='png'){
        $im=imagecreatefrompng($add);
    }
    $width=imagesx($im);
    $height=imagesy($im);
    $img_adj_width=$width+(2*$border); 
    $img_adj_height=$height+(2*$border);
    $newimage=imagecreatetruecolor($img_adj_width,$img_adj_height);

    $color_gb_temp =HexToRGB($color);
    $border_color = imagecolorallocate($newimage, $color_gb_temp['r'], $color_gb_temp['g'], $color_gb_temp['b']);
    imagefilledrectangle($newimage,0,0,$img_adj_width,$img_adj_height,$border_color);

    imagecopyresized($newimage,$im,$border,$border,0,0,$width,$height,$width,$height); 
    header('Content-type: image/jpeg');
    if($extension == 'jpg')
        imagejpeg($newimage,$add,9);
    else if($extension == 'png')
        imagepng($newimage,$add,9);
     //imagepng($newimage);
    //chmod("$add",0666);

}
 function HexToRGB($hex){
        $hex = ereg_replace("#", "", $hex);
        $color = array();

        if(strlen($hex) == 3) {
        $color['r'] = hexdec(substr($hex, 0, 1) . $r);
        $color['g'] = hexdec(substr($hex, 1, 1) . $g);
        $color['b'] = hexdec(substr($hex, 2, 1) . $b);
        }
        else if(strlen($hex) == 6) {
        $color['r'] = hexdec(substr($hex, 0, 2));
        $color['g'] = hexdec(substr($hex, 2, 2));
        $color['b'] = hexdec(substr($hex, 4, 2));
        }
        return $color;
 }
addBorderpng('shahid.png',5);

If you want to do it using PHP, try the PHP GD library: http://php.net/manual/en/book.image.php

Using CSS would be an easier option, using the border property.
