Thanks for the feedback so far...
Peter - I agree 90% with what you are saying (oh how I wish I had started an electronic gadget review web site years ago! - not only would adsense work well but 'Auction Ads' probably would too.. )
But I still think it is possible to achieve the goal from my current web sites (mainly Free Northern Ireland Photos / Desktop Backgrounds / Wallpaper ) - although I am under no illusions that it will be easy, and I will almost certainly need to pay for more than 300 GB Bandwidth per month (mostly because my images are free to download and there are no restrictions on hotlinking).
One thing I know for certain I can disclose is overall earnings for May - $520 (although this was my best month so far by a good bit and looks like June earnings will be down a bit..) - and if you added up the time I have spent so far in my spare time then I have been working for a lot less than the minimum wage so far....
Before I post much more - I would feel a lot happier to have a response to the email below sent to adsense support:-
I am considering posting to forums / blogging about my adsense earnings..Does anyone know if this is at all likely in the near future?
As I understand it - it is OK to state exact earnings. But after extensive searching - I am still about exactly what else I can disclose...
Can I disclose the earnings of specific URLs or only site wide earnings during a specific period?
Can I disclose number of visits during that period?
Can I disclose number of page views during that period?
(I have searched the internet (including official adsense stuff) in vain for a concrete answer to the above questions...).
