Class Random — Image Picker

Simple, local-only web app to randomly select a student by flashing through imported images until one is chosen.

How to run

• Open index.html in your browser (no server required).

How to use

• Click Import Images (or drop image files onto the drop area).
• Confirm thumbnails appear in the gallery; remove any with the Remove button.
• Adjust Spin time (total duration) and Flash speed (initial cycling speed) if desired.
• Press Start to begin the random selection with a visual flash effect.
• Press Stop to immediately stop (optional). When the spin completes, the selected student remains visible.
• Click Pick Again to run another random selection with the current list.
• Use Clear All to remove every image.

Features

• No-repeat mode: enabled by default; each student is picked once per cycle.
• Remaining counter: shows how many students are left in the current cycle.
• Rename inline: click a name under any thumbnail to edit it.
• Save/Load roster: export to a JSON file and import later; also auto-saves to your browser when possible.
• Confetti and sound on selection (can be muted).
• Keyboard shortcuts: Space (start/stop), Enter (pick again), F (fullscreen), M (mute).
• Fullscreen mode for the stage.

Notes

• All processing is local; images never leave your machine.
• You need at least 2 images to start the randomizer.
• Image names are inferred from the file names (without extensions).
