Use PIL to draw frames with ImageDraw primitives, then assemble them with GIFBuilder by setting width, height, and fps, adding each frame, and calling save with color optimization. The builder handles palette quantization and outputs a looping GIF.

Slack emoji GIFs should be 128x128 pixels, kept under 3 seconds, with 10-30 fps and 48-128 colors for smaller file size. Message GIFs can use 480x480 dimensions.

Lower the fps, reduce colors to 48, shrink dimensions to 128x128, enable remove_duplicates to drop near-identical frames, and set optimize_for_emoji=True in the save call for automatic aggressive optimization.

Yes, load the uploaded image with PIL Image.open and either animate it directly by transforming frames or use it as visual reference for colors and style. The skill does not include pre-packaged graphics.

Choppy results come from thin lines, linear motion, and flat colors. Use outline widths of 2 or more, apply easing functions like ease_out or bounce_out for smooth motion, and add gradients, highlights, and layered shapes for depth.
