Extended KotD #14: _SAVEIMAGE

[RhoSigma]

IMHO the name requirements$ for the 3rd parameter was chosen somewhat unfortunate.

It should better be called defaultformat$, as it does exactly that, it designates the default picture file format for all file names without explicit format specification (to be given by a proper known file extension).

In that case the Wiki text could be streamlined to be less confusing and also it could be better marked as an optional override parameter, which just overrides the default default format PNG.
