Uploaded images - Thumbnail sizes?

Upload images - Thumbnail sizes?

 

Hi all

 

I haven't used php for a while now and I'm really stuck on some code I wrote and now I can't work how to change it.

 

I have this function to upload images and create thumbnails. The thumbnails can be either landscape or portrait and I want them to have the same height. At the moment the portrait thumbnails height is equal to the landscape thumbnail width. The dimensions of the thumbnails are the same but the portrait images are portrait.

 

How can I size the thumbnails so they all have the same height. 

 

Thanks in advance for any help or advice on this.
