Introduction
This snippet is fantastic for galleries, cutouts, small webpages, limited sized webpage, forums, anywthing where users can manually edit the webpage and create a "possibility" of screwing it up, this should help!
This does not distort images, whatsoever! it rescales the width and height according to the maximum width/height you allocate.
I am working on developing a function which will cover both in one snippet, but for now, this is what i have :p
How it works (examples)
Insert the function in-between the img tags where width & height paramaters usually would go;
| Code: |
| <?php $img = 'images/myfiles/image1.jpg'; echo '<img src="' .$img. '" ' .width_scale($img,"200"). '>'; ?> |

Just a note: resizing images on \'the fly\' is resource intensive.

On a large scale .. Maybe. But on a small scale, not soo bad.
Do you mean the getimagesize?

Yeah, I would like to see a single function rather than two.

Would this work (not a big PHP user):
Syntax: image_scale($img,"200","250")
Example:
Syntax: image_scale($img,"200","250")
Example:
| Code: |
| <?php $img = 'images/myfiles/image1.jpg'; echo '<img src="' .$img. '" ' .width_scale($img,"200","250"). '>'; ?> |
| Code: |
| ////////////////////////////////////////////////////////////// // Scale images by width+height // ////////////////////////////////////////////////////////////// function image_scale($file,$maxwidth,$maxheight) { list($width,$height) = getimagesize($file); if (($width > $maxwidth) && ($height > $maxheight)) { $new_width = $maxwidth; $new_height = $maxheight; $dec_perw = $new_width / $width * 100; $dec_perh = $new_height / $height * 100; $new_width = $width / 100 * $dec_per; $new_height = $height / 100 * $dec_per; return 'width="' .$new_width. '" height="' .$new_height. '"'; } else { return 'width="' .$width. '" height="' .$height. '"'; } } |

Yea, that one is a lot more advanced, especially since it not only gets the job done great, but it's also more performance-optimized.
