Actually 800x600 is wrong because we use [width]x[height]. True is maximum 640 (width) x 1280 (height).
Dimensions are not the only matter. We use different resolution for printed material and screen. Here we are interest about screen resolution so we use 72 dpi or 96 dpi. (DPI or LPI is dots per inch or pixels per inch).
A normal scanner or digital camera takes the picture in more than 150 DPI so we have to reduce this also to have a size under 200mb for uploading. In InfanView and other image editors dimensions and resolution are in the same window, so when you resize check DPI or LPI to be 96.
Finally there is another way to change image size. Use “save as” “.jpg” and in final window lower the quality to 80%. Of course lower quality is the last option if you want a clear picture.
To see if a picture is under 200mb we right click on the icon of it and we choose “properties”.
