To make a GIF in Falco GIF Animator you'll need several images, that will change one after another.
Choose menu "File" > "Wizard". Then press the "Add" button and select images for your GIF from the disk.
As an example, I chose these pictures:1. 2. 3. 4. 5.
Choose the desired layout (Top left corner of the frame, center of the frame or stretch of the frame).
Enter the time interval between changing images in milliseconds and press "Finish".
In the end you will have the GIF image that can be accessed by clicking the "Play" button.
Save your GIF to disk after.
