Ïmage is empty

I have the same problem, but it is not always, in a couple of times the uploaded file has been ok. The other 20 times that I tested the update file is empty.

“Hi. I have been working with your nice plugin today. All the settings.

But when I try to open an uploaded image-file both on ‘make an order page’ and in my email, the image-file is empty.

Could you help Me with that?”
