Thanks for the replies nabs, Seiken, & porker. Porker, correct, that's just what I was (trying to) say. Nabs, understood, thanks.
Sieken, please correct me if I'm wrong, but with respect I don't think that what you've said is correct. When I upload a photo from my hard drive to this Forum, then in fact 2 copies of that pic actually exist, No? (1 still on my hard drive, the other on some server/s somewhere that drives this Forum)?
Of course I can't check if, with my own PC is turned off/off line, my photo is available to others, but AKAIK, once I've uploaded a picture to this Forum (for example) then it's there and available to anyone visiting this Forum regardless of whether my own PC is online or offline?
So if I'm correct in the above, then the only "advantage" of a picture hosting service for me would be that my picture is stored somewhere else (in addition to my own "copy" still on my own hard drive). This would allow me to see that hosted pic on other devices, even if my own PC was turned off, correct?
As I don't have any other devices apart from my laptop PC (my "smart" phone isn't any more since Swisscom stopped supporting Blackberry) then I conclude that with my own "storage systems" as per my original Q, I do not need a hosting service, correct ?
Thanks all, and BTW, I'm definitely NOT "sniping" at anyone who does use such service, but just wondering what, if anything, I'm missing.
