Matt,
I am in exactly the same position! I have managed to increase the size of the images by changing line 20 of images.php from 480 to 580 which increases the size of the main photo to gave a much better display. However, this has had the effect of pushing the border to the right, in the same way that the thumbs are automatically displayed. I haven't got too much of a problem with the thumbs being displayed like this but I would really like to get the border around the main photo back centralised.
I know it is something to do with the css but I have no idea where or how to do it. Any help gladly appreciated.
Matt - for your info, my line 20 in images.php now reads:
`"><?php printCustomSizedImage(getImageTitle(), 580); ?>`
Update:
Just found out that if you delete lines 623-625 from photo.css, it removes the border from the main photo completely. Lines as follows:
`#photo_container img {
border:10px solid #fff;
}`
Doesn't solve my problem as I would still like the border centralised but may assist you?
Thanks
Mike
