I think the whole reason everything is small is because you're using a very high resolution. The only other option you have is to use some sort of extension in Firefox, such as Image Zoom (although I've never tried it).
Why did you send me this in a PM. This is the closest thread (in topic) started by you that might have something to do with this, so I will post it here for everyone to see, and benefit from the answer.
I've downloaded fedora core 7 i386 from fedoraproject.com
how can i burn (bootable) on dvd?
there are lot of .img files
With nero or some other burn program? My God, read the documentation to whatever burn program you have, and look for tips at the website where you downloaded the image.
Why does no one ever do the obvious? Or, if they did, at least list the things they tried to avoid getting ripped like this.
