If you drag and drop an image file onto the main window, the file will be inserted where it was dropped.

If you change the size while pressing the Shift key, the aspect ratio of the image is retained.

You can also change the position of the image by entering values for the X and Y coordinates on the image object information palette. You can resize the image by entering values for the W (width) and H (height) on the same palette.

Pressing the up, down, right, and left arrow keys on the keyboard moves the image object pixel by pixel.
