Google Maps - Show in Greyscale

[Billywiz]

Hi zinc, I never implied or suggested that this extension doesn't work but I can't see the point of putting a demo up
to view before purchasing if you cannot see it working.

i did not enter an apikey because was not required until google changed the rules
of course, the extension DOES work, otherwise i would removed it from the shopping site
the idea to have a demo was to show a sample, however, nowadays this became obsolete and i won't pay for an api key just to have an active demo when many professional developers know that it works
new potential customers that contacted me have seen the extension working on other sites; also the member called zinc gently posted a link to show an actual, live and working [btw, awarded] site
having here a forum, with active and collaborative members that eventually post their work, i don't see the point to pay for just to have a demo, i think a google maps gateway is not the incomes source for anyone...
that's all and move on dear mates...
