What are the recommended dimensions for Slack emojis?

For optimal display, the skill recommends a resolution of 128x128 pixels for emojis and 480x480 pixels for standard message GIFs.

Can I use my own images with this skill?

Yes, the skill supports loading user-uploaded images via the PIL library, allowing you to animate existing assets or use them as a reference for new designs.

How does the skill handle Slack's file size limits?

It implements several optimization strategies including reducing the color palette (48-128 colors), lowering FPS, and removing duplicate frames during the save process.

What dependencies are required to use this skill?

To function correctly, the environment needs the Pillow, imageio, and numpy libraries installed for image processing and file assembly.

What types of animation effects are available?
