UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? Iphone photo format

Hi

a member is requesting that I allow photos from Iphone to be uploaded to the forum as attatchment.

At the moment I have this setting
.gif,.GIF,.jpg,.JPG,.txt,.pdf,.PDF
Can I add format to this line in order to be able to upload Iphone/Ipad photos?

Thanks
Morgan
