The pictures on desktop are too small to have a clear look. You can move the cursor to the picture you want to see, right click it, and left-button click the “browse” option in the option menu popped up.

Then the picture will be displayed in real size. You can zoom in or zoom out it by pressing [+] and [-] on keyboard. Arrow key is used to move the picture if it is too large to be shown completely on the screen.

Press [ESC] to quit the browsing mode.
