Animations: Using GifBuilder

Animations: Using GifBuilder to Make an Animation

First you need to move your images to the Macintosh.
Once your files are on a Mac, start up GifBuilder. You should see a blank window for your frame information and a small Untitled.gif file.
Choose the File/Add Frame menu item to add a new frame. Select the frame to be added. Unfortunately, you can't select multiple frames at once, so you will have to go through this process for each frame individually.
Once you have loaded all your images, you can select individual ones or groups of them (by shift selecting). You probably want to select all the frames and then choose the following settings in the Options menu:
- Transparend Background / Based on first pixel
- Disposal Method / Restore to background
- Frame optimization
You may wish to change other parameters as well, depending on your movie. For example, you can use the Loop option to make the animation loop continuously.
You can use the Animate menu to test your animation.
When you are ready, use the File/Save menu item to save your GIF animation.
Move your finished .gif file back to the web-server machine in order to make it available over the web. (If necessary, see the instructions for moving files to and from the mac.)
To insert the animation into a web page, simply link it in with a <IMG SRC="file.gif"> tag as though it were a still .gif image.
