Ok, so you are resizing your VIEW of the picture, not the picture itself. For posting you want to resize the actual picture.
I use Adobe and don't have windows so can't help you with M$ Photo Editor. In Adobe Photoshop there is View:Zoom In, View:Zoom out, View:Zoom %. Those change the view size. Then there is Image:resize image which actually modifies the image.
Ahh google to the rescue.
Resize an Image - you can resize an image BUT REMEMBER, if you have a small image and you want to resize larger, the image may become pixelated or distorted because the resolution is too low to allow for resize. It's much better to have a large image that you resize smaller than to try to make a small image larger.
1. Open Microsoft Photo Editor
2. From the File menu (or open icon), choose Open. Navigate to where you have your photos or images stored. Click on the one you want to open.
3. From the Image menu, choose Resize
1. You can enter width & height numbers or you can use percentages to resize. You can also select which unit of measurement to use - inches, centimeters or pixels.
2. Do NOT check Allow distortion unless that is what you want. If you leave it blank, you can type in a number in the width and have it auto calculate what the height should be without distoring the image.
For web posting choosing 640x480 pixels fit nicely onto a screen within a web browser so select a width of 640 pixels and let it calculate the height. After you do this you SHOULD be able to view the picture at 100% and have it fit on the screen.
