Remove Exif

Urgent fix needed!

My website is a simple classified ads directory. When a customer goes to upload a listing (which includes text info and pictures) the pictures rotate when displayed. The tech team for my theme, listable, seem to think the Exif rotates the pictures and therefore I need to remove it completely.

I would need some help to just simply remove the exif (if that is a simple thing to do).

Many Thanks,
