Error, when I cancel the upload. Not every Thumbnail was created.

Hello,

I hope you can help me.
When I cancel the upload while uploading pictures, the uploadskript stops immediately (I think).
Thats a problem, because I calculate from the uploaded Picture 2 Thumnails. But when I cancel the upload, it could be happen that only one Thumbnail was created or no one. What cann I do, that the process end correctly.

Thank you,

greets Stefan
