Can I use my own images as a starting point?

Absolutely. The skill can load user-uploaded images via PIL to animate them directly or use them as a creative reference for colors and style.

How does it handle file size limits for Slack?

It provides automated optimization strategies like reducing color counts to 48-128, lowering FPS, and removing duplicate frames to ensure compatibility.

What types of animation effects can I generate?

The skill includes logic for sophisticated effects such as pulsing (heartbeats), bouncing, rotating, fading, sliding, and even complex particle explosions.

Does this skill support Slack emoji constraints?

Yes, it specifically targets Slack's 128x128 recommendation and includes optimization tools to keep file sizes small enough for emoji usage.

What Python libraries are required for this skill?

The workflow relies on standard image processing libraries including Pillow, imageio, and numpy to handle frame rendering and GIF assembly.
