Enable copy instead of decompress of the image

[s00500]

Hi,
The decompression of the zip file takes a rather long time in the build process... so my idea is to enable copy instead of decompress

I could supply a quick PR if you want to :-)

Greetings,

If you want to add something that is optional then sure. I am not sure what the implications if its default. Might break build systems
