You'll have to devise a method which is "secure/tight enough.
The connection presumably does not need to 'survive' for very long for you to see if you're able to get s picture?

Very probably, but probably thinner than you would think was possible

Further more I read that a one oz of gold can be pressed out into a 1 meter squared sheet, with a thickness of 23 atomsVery probably, but probably thinner than you would think was possible

Further more gold is a very good conductor or electricity which in this case will mean a better connection and hence a better signal
But sadly I went though the process to order it and they wanted an extra fiver for handling charges

That, coupled with its resistance to corrosion (such that the 'better connections' are maintained) is precisely why it's used in such situations (whether always 'necessarily' or not is perhaps a different matter1).

Just for giggles!
Please correct me if my logic is flawed!
...and here I am only talking about the plating thickness of electronic components!
Typical coating thickness of gold in electronic connectors is 0.8 microns, over 1.3 microns of nickel.
Assuming 24K gold.
...1cm³ of gold would cover an area of 12500cm² at 0.8 micron.
...1cm³ of gold has a mass of 19.32g
...1g of gold has an area of 647cm²
...1 ounce of gold would have an area of 18'342cm² or 1.83m²
(...or 2.01m² if the ounce was Troy!)
...currently gold costs @£47.80/g
...1cm² of gold plating would cost 7p in gold alone!
That gold plated connector is a bargain!
And some extra info:
Gold leaf can be hand beaten to thinner than 0.1 micron - that's approximately a 200 (Edit: 390 after further calculation?) atom thick layer.
Covering an area 8 to 10x greater than above.
Edit:
Although I have just found this on wiki: "A single gram of gold can be beaten into a sheet of 1 square metre (11 sq ft), and an avoirdupois ounce into 300 square feet (28 m2)"
So my guesswork may be a little off!

I cannot find fault with your arithmetic.Please correct me if my logic is flawed! ... ...and here I am only talking about the plating thickness of electronic components!

However, per some of the edits you added after I started writing this, in terms of
Mr Google tells me that the diameter of a gold atom is about 0.000144 microns. If that is the case, if they could be jammed together 'across diameters', 23 would seem to amount to some 0.003312 microns, some 2,415 times smaller than the 8 microns of your plating. Hence, in relation to AstonHill's (23 atom) rather than your (8 micron typic electronic plating) situation, I g of gold ought to cover about 1,562,505 cm² (aka about 156 m² or 0.0156 hectares) - which is much greater than AstonHill's suggestion of 1 m², but a lot less than @JohnD 's suggestion that perhaps 1 hectare might have been intended.
Assuming that I've got my arithmetic right, Is it perhaps that case that it's not possible to cram gold atoms together anything like as tightly as I have assumed?
