If you resize to 800 x 600, 1024 x 768, or 1280 x 1024 you shouldn't get
too many complaints from most viewers.

As a rule of thumb limiting the long dimension of any image to 1024
should work and then saved with enough compression to bring the file
size to around 300Kb or less.

Here is a shot of a P-51D resized to 1280 x 868 and 293Kb:



Savageduck: I've seen your posts on this & other news groups. I would
say they rank right up there with the best of them.


Thanks for that Dale. I enjoy your more prolific output in the various
NGs I have shared with you.
....and I am somewhat envious of your proximity to so many fine subjects
at work.


To the original poster: I use Irfanview to resize for news groups. I
have taken to using 1280 x 853, with a quality of 80%. Pics come out
approximately 100kb - 200kb. Going lower in percentage would probably
not affect the quality here noticeably, but would yield a smaller
picture still.

Lately I've been processing images with Capture One with no quality
reduction & resized to 1280 x 853. I then have to resize to the same
size but a reduction in quality of %80. These pictures come out 200kb -
300kb, a little larger than I like. I may consider downgrading further.


I am a Mac user and do my editing with CS5 and usually save the
finished product with crop tool presets setting dimensional proportion
& size. I usually finish to a 12 x 8 crop, unless other
proportions/aspect ratio are needed for the intended result. I save the
CS5 created JPEG at maximum quality, with file sizes of anywhere
between 3-14Mb.

My default viewer on my Mac is "Preview". With that it is a simple
matter to resize for online distribution for both a decent screen size
Currently I use 1280 as a long edge dimension for most of my shared
images. (Preview has several convenient presets to use). I then save
the resulting reduced jpeg file usually to less than 300kb in this
case of a screenshot of one of my first bits of HDR experimentation
taken at Schipol in 2009, down to 184kb for a 1280 x 720 @ 72 ppi image.
