I've fixed it by uploading a pdf instead of the original jpg, but I'd dearly like to know why firefox thought it should be scaled like that.

Apparently the justification for this is that it makes Firefox work better on PDAs and other small-screen devices. Firefox3 introduced "automatic image scaling" which IE has had for some years. Here's a post where someone describes his frustration with image scaling in IE7 (at least as far as I know Firefox doesn't get confused by DPI settings):

What annoys me about this in FF3 is that the feature is on by default and the standard preferences dialog doesn't offer a way to disable it. Instead you have to go into about:config as described here:

Of course this doesn't help page designers who can't tell whether their visitor's browser has scaling enabled or not.

Before someone else corrects me: Yes, I just realized this has actually been around for a while before FF3. In fact it was more like FF1.4. I believe the algorithm changed some in FF3.

The point about the configuration setting being buried is still valid, I think.

Wouldn't this do the trick?

In fact it makes for a real mess. Hopefully these days everyone has some sort of pdf reader, so that's going to have to be the solution, but it's far from idea. No application should be making decisions for me unless I ask it to. If I want to use such a settings, say for the EeePC, then I, as the user, should enable it. This is absolutely crazy.

Thanks for pointing me to that blog. It certainly explains what's happening.

Hi Anne

Hope you don't mind me butting in on this (as a newbie round here!).

If you would like to provide a URL for the page I'd be more than willing to take a look at it for you.

Thanks for the offer, Matt, but I don't know whether the change I've made will obscure what was happening. It shouldn't, I've just replaced a jpg with a pdf and changed the link url. Still, if you can see anything that gives a clue I'd be really pleased. The launching page is http://eastpenninekoi-club.co.uk/membership.html
