increased the Delay much more (now 1.5s).

Lower Delay will rise errors when rendering big images. 
My system Win7 64 (slow HD) reports following error on lower Delay: 
---
Reached EOF while decoding PNG
Cannot open input file
Cannot create backend data
Unknown fileformat
---

Maybe Delay should be bound to the imagesize. Or is there a better solution to wait for povray to finish the writing?
