Open external window from html loaded into flash

hi again,

I know it’s possible to open external window from dynamic loaded html into flash - via targed tag in html - but is it possible to open this window in custom dimension? Is it possible to use JS code in dynamic loaded html into flash? I just want to open via image link external window (custom dimension - i.e. 200x200 px) from html dynamic loaded into flash and load into this window image file.
