What are the recommended dimensions for Slack emojis?

Slack emojis should ideally be 128x128 pixels to ensure they look sharp and load quickly. For larger message GIFs, 480x480 pixels is the recommended standard.

Can I use my own images with this skill?

Yes, the skill is designed to work with user-uploaded images. It uses the PIL (Pillow) library to load, resize, and animate existing assets or use them as a stylistic reference for new creations.

How does this skill keep GIF file sizes small for Slack?

The skill employs several optimization strategies including reducing the color palette (often to 48-128 colors), lowering the FPS, removing duplicate frames, and using specialized 'emoji mode' settings during the save process.

What kind of animation effects are supported?

The skill supports a wide range of motion concepts including shaking, pulsing, bouncing, rotating, fading, and particle bursts, all powered by a dedicated easing library for smooth, non-linear movement.
