Default Images very large

Hi,

I've been trying to post some high resolution images, but the size on the post is very large, even if I edit the height and width before upload.

Any tips to posting images with a reasonable size but high res. for reading of component numbers, etc?

This only works when printing to paper, where your printer can be instructed to place ink dots closer or further apart. So you can have high resolution (lots of dots) and still a fairly small picture, by printing ink dots very close together.

Things are quite different when you're dealing with a contemporary digital monitor or TV. The pixels are a fixed distance apart (you can divide the screen width by the number of pixels across to estimate the distance between pixels).

This fixed pixel spacing means the size of the (on-screen) picture is fixed by the number of pixels in the image. You cannot change the number of pixels without also changing the size of the displayed image!

Still more annoying, there is no standard whatsoever for pixel spacing. Some modern phones and tablets with very small screens have been marketed on the basis of absurdly large numbers of pixels. Net result: uselessly-close pixels, so that a 1000-pixel image appears very tiny.

At the same time, you can buy an 80-inch TV with only 1920 pixels across the entire screen width. Individual pixels are now quite large, and that same 1000-pixel image will take up more than half the width of that gigantic TV.
