Web Hosting Talk : Web Hosting Main Forums : Programming Discussion : PHP Image Manipulation Question

[SI-Chris]

I have been searching Google and can't figure out how to do this. I have a thumbnail builder in PHP and there's one thing I want to add but am not sure how to do it. Perhaps someone here can give me a code example.

Say I created a thumbnail that's 100x50, and I want to add 25 pixels of white space at the top and bottom so the image is exactly 100x100. I don't know how to add the white space. I am using GD to generate the thumbnails.

I don't think GD has built-in commands to change the canvas size. I'd just create a new image 100x100 white background and insert your thumbnail into it at position (100-w)/2, (100-h)/2.

why not make the container the thumb displays in a certain size and color using css.?

#thumb_container{background: #FFF; padding: 25px 0 25px 0;}

<div class="thumb_container"><?php echo $my_thumb ?></div>
