Sorry if I gave you the idea we were at loggerheads. I just thought it was a great discussion and exercise. Like you I've searched the web re information on this issue and like you have found it conflicting and bias towards the 72 dpi. I just want to get to the truth of the matter.

Plus there's this high res images taking longer to download thing, which I know you're not going to accept but I have had it happen to me while on dial-up.
No, I agree. A hi res image of 24000 x 24000 pixels sent in an image format with no compression is horrendous. But I think that just confuses the current issue.

Thanks for your input Risto. I keep intending to create a tutorial re this issue, but it does tend to hurt your head!
