Custom BCCODE Image Resize

[richardevans123]

Hi All,

I'm trying to add my own Custom BBCODE so that I can make my website more Retina Display Friendly. I've done a lot of editing of the style already, but my signatures don't have the retina graphics. What I'd like to have is something like;

"[imgr 686x126]enter your url here[/imgr]"

Currently, I've got it set up, but it doesn't actually show the image. The HTML replacement is as following:

<img src="{URL}" height="{NUMBER1}px" width="{NUMBER2}px" alt="{L_IMAGE}" title="{L_IMAGE}" />

Any ideas?

Thanks
