image size

[chrisparr21681]

i need to check that images are being uploaded through a content management module at a certain size, if they exceed the 10k or are not 120x120 then i want an error message to popup

Certainly, in IE at least, you can create a new image object, assign the source, and then query the width and height attributes... I'm not sure how well this works in other browsers, but give it a go anyway.

Having said that, you cannot check the filesize client-side (without using an IE-specific activeX control)... So you'd be far better off doing this whole thing server-side. And you must have access to server-side scripting to be writing your CMS anyway, I would have thought.

Hope this helps,
