It is possible to place pictures in various positions in the crossword grid taking up one or many squares. Select Paste image... from the Edit menu to insert an image from the clipboard, or Insert image file... to insert an image from a file. You can insert either a bitmap or a Windows picture (metafile). You will be prompted for some options for pasting the image. To put a background image in a single square, use the option in Square Properties instead.
The Left Square and Top Square options determine the co-ordinate of the top-left of the image in the crossword grid. Set the Squares Wide and Squares High to the width and height (in grid squares) you want the image to have. It must cover an integral number of squares.
Check the Add Border box to have a line around the image.
The Arrow settings allow you to add a little arrow coming from the image, useful in conjunction with a clue squares crossword. Grid X sets the left square that you want to have the arrow, Grid Y sets the right square. You can choose which direction you want the arrow to point in.
You can change the image's properties once it is in the grid by right-clicking on it with the mouse. You can also delete the image this way.
You cannot undo adding and removing images.
