aaaah, it looks like a little light is being shed on the problem here, it does indeed look as if the forum is affecting the size of the images you've posted.
The image 9863b9d40dhir.jpg when downloaded from the forum is coming in at just 951x1189pixels, whereas looking at your latest post the true size of the image on your own PC is 2400x3000pixels, a much healthier resolution
You can rest easy mugsman, all is well, all my calculations have been based on the forum compressed images
sleep well
