The sizes for all dialogs are set in the file fckeditor/editor/_source/internals/fckcommands.js , but as you'll notice this is the unpacked source, so changes in this file won't affect your FCKeditor install.
To change the dialogs their sizes for your installation you'll have to repack the source or change the packed source.
To edit the packed source you'll have to edit two files:
fckeditor/editor/js/fckeditorcode_gecko.js
fckeditor/editor/js/fckeditorcode_ie.js
Search for the path of the dialog you want to resize (use the unpacked source as a reference for this), then change the width and height dimensions of it.
E.g.
To change the image dialog its size search for 'dialog/fck_image.html' within the two files and you'll find the command:
FCKDialogCommand('Image',FCKLang.DlgImgTitle,'dialog/fck_image.html',450,400);
Now just change 450 (width) and 400 (height) to whatever dimensions you like, resave and clear or disable your cache before testing.

RE: HOWTO - Set dialog sizes
Glad that I could help.
Christophe,
Thanks for your kind words.
Indeed the ImageManager works differently. For the manager window you need to be in 'ImageManager/manager.php' and change the dimensions in 'window.resizeTo(600, 460);' (line line 31); for the editor window this is the string 'window.resizeTo(673, 531);' (line 28) in file 'ImageManager/editor.php'.

RE: HOWTO - Set dialog sizes
But hmmm, 700x700 is no problem for me, but while trying larger values I found out that IE just doesn't seem to be willing to stretch the window behind the point where the bottom border falls out of the screen. So what I think what happens is that with you the ImageManager window is created quite close to the bottom of your window so that IE limits its height. Try adding the command 'dlg.moveTo(0,0);' just below the creation of the window on line 211 in 'ImageManager/fckplugin.js' and see if that helps...

RE: HOWTO - Set dialog sizes
(for info, I found that 'window.resizeTo(640, 520);' seems to be the best setting in 'ImageManager/manager.php').
A great day to all.

Re: HOWTO - Set dialog sizes
So far:
'dialog/fck_image.html'
original - 450,400
modified 2 places both files - 600,400 (looks ok)
'dialog/fck_image.html'
original - 400,330
modified 1 place both files - 600,330 (looks bad but works)
Re: HOWTO - Set dialog sizes
I noticed that sajax works well with pages in the dialog directory. They use:
var oEditor = window.parent.InnerDialogLoaded();
Then call sajax by: oEditor.window.parent.sajax_do_call( 'wgMyFunction', [ajaxArg], UpdateImageAjax );
I tried to use sajax_do_call outside the dialog window with the ImageManager using:
oEditor = FCKeditorAPI.GetInstance('InstanceName').EditorWindow.parent;
oEditor.sajax_do_call( 'wgMyFunction', [ajaxArg], UpdateImageAjax );
But get oEditor is not a function error.
Is there a way to use sajax_do_call outside the dialog window with the ImageManager?
Please help...
