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"?
 
you don't need imagecopy to do this; in imagecopyresampled, you have int_src_x and int_src_y, which will allow you to take the original image from different co-ordinates - then just use imagejpeg/imagepng or some similar to output the image to file/screen
 
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...

sounds like you weren't doing the calculations to keep the aspect ratio for non-square images? i assume you were just using a fixed size for your new image?

but not that it matters now anyway.... :p
