Hi Greg,
Cheers - I owe you a pint at the next users group meeting!
I'm much better at server side scripting, just never really got it together properly with client side browser manipulation stuff. I can tweak and modify existing javascript quite well and sometimes get things going from scratch but had really no idea on this one!

I'll give it a good bashing about later today and make such thay the numbers it gives relate to the image resize / mogrify results with Imagemagick and tweak as required. It should be just about the last bit of that page in my CMS then, its a facility to allow users to upload and resize images either as a set of pre-sized or one user defined sized image on the fly for inclusion into pages on the site.
The idea of preserving the aspect ratio on resize is quite important as it's designed to be used by totally non-technical users! :-)

Thanks again!

Phil
