Increase size of Image Properties dialogue?

Hi all,

This one has evaded me all week. I'm no developer, but I was pretty sure I could figure it.. but now I'm stumped.

How can I increase the size of the Image Properties (and preferably also the Link Properties) popup dialogue?

There are places, such as in the fckconfig.js, where it appears that the popup sizes are exposed, but changing the values makes absolutely no difference. (I am of course clearing all caches and confirming that changed values are being processed)

To make it clear which windows I'm talking about I'll reference my thread about it in another forum:

Look at the 5th post with the screengrabs in it.

I'm also pretty sure that there will be different places to make a change depending on which opening method is being used. I'm using the OptionsOpenMode="ShowModalDialog" which affects IE and seems to remove the resizing ability as well.

I have search the forums here, but the references I have found are all for earlier versions and files that no longer exist.

Any advice is appreciated,
Rob
