PHP cut section out of image, possible?

[gumbald]

Thought this deserved a separate thread to my other, even though it relates to my same page, it's something I could need to know in general.

I'm creating an image gallery: http://gumbald.co.uk/photos/, but after putting some portrait ones in there, I think they look silly. So I want all my thumbnails to be landscape.

For the portrait photos, I envisaged this would be a section cut from the middle of them. However, I can't find a way to do this automatically. I don't want to have to make the thumbnails myself, I've got a perfectly good upload page which puts entries into mysql also.

Can it be done? Something similar to "imagecopyresize"?

I've fixed this, it was an imagecopy() that was needed after an imagecopyresampled()

That didn't seem to work, I was getting black bars down the sides of the images. I do an imagecopyresampled to take the image to the correct width, then cut the section out of the middle of it...

Yeah, I've done lots of calculations But it's working fine now
