I've got a problem, if I use IE 6, 7 or 8, the pop-ups will not look normal. The width is resised to the preset width, but height is still original, so image is reshaped. \\
PLease see: http://travel.synyan.net/%e8%b6%b3%e8%bf%b9/ under IE 6-8.
I've checked the backend panel, it is probably because:
If pop up window image is too wide, then resize it to pre-fixed width. the height will be adjusted accordingly.
(this function only works when your theme supports wp_head()-hook)
So, how can I make sure my theme supports the hook?
