I have found that the majority of photography forums that I have visited have 1024 x 768 pixels at 96dpi as thier standard. 96 dpi is the 'best' resolution for LCD and similar flat screens. On my laptop me screen resultion is set to 1600 x 900 (16 x9 is the standard ratio for widescreen TV). Most older CRT monitors used an aspect ratio of 800 x 600 (4:3) which gives a squarer image which frequently results in the top and/or bottom of the image being cut off - hence you have to scroll the image.
I had a look at the metadata for you last images and it is 800 X533 pixels. Taking 96 dpi = 100 pixels as an approximation, your image should and does display as 8" x 5 1/3" on my screen (800/100 pixels per inch x 533/100 pixels per inch). It was uploaded as 800 x 800 and resized by the browser for the display size of 800 x 533.
When resizing images to upload, you will be pretty much correct if you set the number of pixels equal to the height and width in inches (that you want your image displayed at) multiplied by 100. eg. to display at 10" x 8" the number of pixels would be 1000 x 800. and that will work for most modern LCD, plasma etc screens. For older CRT monitors the multiplier is 80 instead of 100 is generally used.
One way you will have an image that is "right" for one technology but will be either smaller or larger than the preferred size for the other technology. You can't please all of the people all of the time:D
From memory, the last figures I saw showed that close to 40% of internet users still use the 'old' CRT technology, 800 pixels on the horizontal and 600 pixels is fine for the old technology and still gives a 8" x 6" image on the newer flat screen which is generally adequate for the type of images we are displaying on the forum. And as Niel said, this as also the forum's preferred size.
Hope I haven't made the water any muddier:;
