Amazing. I think this may be a record ... resurrecting a nearly 3 year old thread and adding no meaningful information.
I can't even believe someone went back that far in the forum to find this.
...this is what the search facility is for - hopefully it enables us to find answers without starting new threads on previously discussed topics.
My post was not an attempt to contribute meaningful information, but a request for information... I asked two questions that no one has attempted to answer.
I was considering posting an image of mine which I hope is marketable and valuable, so I was wondering if there was anything to prevent anyone stealing it - there appears not to be.
The scene in the photo in question is not a unique unrepeatable shot (any one can go there an produce a similar shot) and no-one could produce a salable 24 * 34" print from a 2MB file, but, even if not for this shot, I consider that the questions are still relevant.
For a post on IQ, a link to a zoom-able full res (300MB) file on a copy-protected site might be a possibility... but members frequently get round this by posting blow-ups of small sections of the image.
I would appreciate it if someone could contribute some meaningful information to this thread.
