Gallery File Rules and Limits

Step 1 — Check limits before upload

Step 2 — Handle common upload errors

• “No file selected” means picker state is empty.
• “Audio uploads must be .ogg or .mp3 files…” means wrong format.
• “Audio files must be under 20MB.” means size overflow.
• “Telegram uploads are limited to 10 files per batch.” means split batch.

Step 3 — Retry with cleaned batch

1. Remove invalid files from selection.
2. Split oversized batch into smaller groups.
3. Run upload again and confirm success count.

Common mistakes

• Uploading unsupported audio extensions.
• Submitting more than 10 oversized files in one Telegram batch.
• Assuming silent failures will self-recover.
• Keeping failed assets in script steps.
