It is important to know how large the file you are going to publish is, both because of the appropriate quality for photos and to avoid uploading too large files into the web management system.

The easiest way to see the size of files is to right click on it and select "properties", then a window will appear where you can see how "heavy" the picture is under Size. If you click on Details you can see how big it is in pixels and in what resolution. For example here where the picture is in 72-point resolution but the size is 3651x3207 pixels.
