Image viewer for VERY BIG image files

[Mike]

I have a couple of .tif images that I want to view. They're roughly 240mb each. They crash Microsoft Office Picture Manager if I try to open them in that, and they take a minute or so to open in Irfanview.

Is there a program around that specialises in opening and panning etc. large images? I'm only new to Irfanview, but I find it annoying when trying to pan the image (which is 9800x8000).

Thanks,

Mike.

press enter within irfanview and it will display the image fullscreen with a rough resize filter...

why dont you use the resample (ctrl + R) to knock it back to 640x480 so that you've got a small version and a large version.. then use the small version for previewing?

Not really suitable for this image and besides, 640x480 is less that 7% of the original size you don't get to see much at that size even at 1024x768 its small

While we're on the subject of Irfanview... It loads this 240mb tif image in about a minute (maybe less), yet a 4mb MrSid image I loaded took closer to 4 minutes (mind you, uncompressed the MrSid was also around 240mb).

Cheers,
Mike.
