Weird one - I have an SD card full of camera images which worked absolutely fine, without any hassle on my GFs laptop but I've just tried to open them on my Macbook to find every JPEG is completely corrupt. They don't work in Preview, Safari, Photoshop, Pixelmator etc. Only around 10 images on the entire SD card actually work, which is incredibly odd. Why them and not the other hundred odd photos Any ideas? There's also AVI videos taken on the camera too, which aren't working either.
