I've tweaked that code a bit to get it to fit in a bit and display a message. You can find a preview of it here.

You can put this in either you headers or your footers. You may have to edit the colors in the CSS on top if you are using a custom theme.

Also note that the icon that is displayed is from the silk icon set from famfamfam.com which is licensed under a Creative Commons Attribution 2.5 License.

Code:
 

<style type="text/css">
div.resized_image p {
margin: 2px;
margin-top: 0;
font-size: 8px;
/* Awesome icon from here: http://www.famfamfam.com/lab/icons/silk/ */
background: url(http://i242.photobucket.com/albums/ff244/9861_omikron/error.png) no-repeat;
padding-left: 20px;
color: #333;
}
</style>
<script type="text/javascript">
$(document).ready(function() {
(
function(maxht, maxwt, minht, minwt) {
var imgs = document.getElementsByTagName('img');
// Image resizing function
var resize_image = function(img, newht, newwt) {
img.height = newht;
img.width = newwt;
$(img).wrap('<table><tr><td class="tborder"><div class="resized_image"><a href="' + img.src + '" target="_blank"></a></div></td></tr></table>');
$(img).parent().before('<p>NOTE: This image was resized. To view it full-size, click on the image.</p>');
$(img).parent().after('<p style="text-align:right;background:none;margin:0;padding-right:3px">Image resizing script by <a href="http://aetus.net/217/programming/automatically-resize-large-images-with-javascript/">Aetus Designs</a>.</p>');
};

for (var i = 0; i < imgs.length; i++) {
// Set a variable for the current image to make the code make more sense.
var img = imgs[i];
if (img.height > maxht || img.width > maxwt) {
// Use Ratios to constraint proportions.
var old_ratio = img.height / img.width;
var min_ratio = minht / minwt;
// If it can scale perfectly.
if (old_ratio === min_ratio) {
resize_image(img, minht, minwt);
}
// We need to do some magic now.
else {
var newdim = [img.height, img.width];
// Sort out the height first.
newdim[0] = minht;
// The logic behind this is that if ratio = ht / wt, then wt = ht / ratio.
newdim[1] = newdim[0] / old_ratio;
// Do we still have to sort out the width?
if (newdim[1] > maxwt) {
// Just do what we did with the height
newdim[1] = minwt;
newdim[0] = newdim[1] * old_ratio;
}
// So yeah, resize the image
resize_image(img, newdim[0], newdim[1]);
}
}
}
}
)(500, 500, 500, 500);
});
</script>


If you want to adapt this to fit with another forum system, you might want to look here: Image Resizing Script.

Oooh, nice one. This'll be useful for my SMF forum.

I take it this works with SMF 2.0 RC1-1 too; not just 1.1.9? :)

Hi Celebrus

This code looks very interesting .. I have a couple of questions:

1. I run an smf 1.1.0 forum, using a custom template (the site linked in my sig) - can you tell me where this code should go?

and ..

2. Does this code work for posts already made?

Thanks in advance.

To Caelum and mack, it should work since it doesn't use anything specific to SMF 1.1.x, but you might have to change this line because the CSS is probably different.

Code:
 

$(img).wrap('<table><tr><td class="tborder"><div class="resized_image"><a href="' + img.src + '" target="_blank"></a></div></td></tr></table>');

EDIT: I'm not at home, so when I return I will test this properly. The computer I'm using isn't exactly up to par with my being able to test anything.
