renames JPG to jpg
I hope the answer to this is simple! Using DFP, when a user uploads an image such as 1234.JPG the image is renamed to 1234.jpg. This doesn't matter on my Windows testing machine, which isn't case sensitive - so the image dislays; but on the live Linux site, the 'image not found' error is dsplayed. If I change filename in the database to lowercase jpg, the images are displayed. Obviously, I cn't continue to do this after testing.
Is there a simple setting I need to make to stop it changing capitalisation?
