Resizing

What picture dimensions to people prefer for posting here? Most of my
attempts so far have been too large or too small, and I can never
remember from one time to the next what settings I used.

I've experimented with IrfanView and Digital Photo Professional.

First, there's the size in pixels. Get it too small and you end up with
a 30kb postage stamp. Too big and it falls off the screen after taking
ages to download. (I had to give up looking at the recent Space Shuttle
series as there just weren't enough hours in the day.) DSLRs are usually
3:2, but widescreen monitors are 16:9. Do people still use 4:3 CRTs any
more?

My originals come from an EOS 350D. It was the bee's knees when I bought
it 6 years ago, but it's practically Stone Age technology now. Original
file sizes vary from about 2.5kb to around the 4kb mark. 8 megapixels.

Then there's the scanning resolution. Too small and the image is fuzzy,
too high a count and it's a waste of bandwidth.

As I mentioned before, I don't like Thunderbird. I'll try Opera one of
these days. I used to use Turnpike, but V6 won't work under 64-bit Win 7
Home Premium and I haven't yet been able to track down a copy of V5.

The Duxford Air Show http://duxford.iwm.org.uk/server/show/conEvent.3563
this weekend, and Saturday's weather forecast is reasonable (for England
in September anyway), so a few good shots might be possible.
