GIIL: Cloud Image Downloads

Download cloud-hosted images for visual debugging

New to ACFS?

Go to Choose Your OS
Goal

Download cloud-hosted images for visual debugging with giil.

What Is GIIL?

GIIL (Get Image from Internet Link) downloads full-resolution images from cloud sharing services directly to your terminal. When a user shares a screenshot via iCloud, Dropbox, or Google Photos, GIIL fetches the actual image for AI agent analysis.

This bridges the gap between mobile screenshots and terminal-based debugging. Users capture bugs on their phone, share a link, and agents can immediately view and analyze the image.

Multi-Platform

iCloud, Dropbox, Google Photos, Drive

Full Resolution

Downloads original quality images

Visual Debugging

AI agents can analyze images

Album Support

Download all photos with --all

Supported Platforms

GIIL extracts images from these cloud sharing services:

iCloud

share.icloud.com/*

Dropbox

dropbox.com/s/*, dl.dropbox.com/*

Google Photos

photos.google.com/*

Google Drive

drive.google.com/*

Essential Commands

Download image from cloud link
Save to custom directory
Output JSON metadata
Download all images from album
Show all options
Note
Always wrap URLs in quotes to prevent shell expansion of special characters.

Visual Debugging Workflow

GIIL enables a powerful visual debugging pattern for AI-assisted development:

1

User Screenshots Bug

User captures the issue on their phone or desktop

2

Share Cloud Link

User shares iCloud/Dropbox/Google Photos link with agent

3

GIIL Downloads Image

giil "<url>" fetches full-resolution image to working directory

4

Agent Analyzes

AI agent can now view and understand the visual context

bash
# Example: User reports UI bug
# They share: https://share.icloud.com/photos/abc123
# Download the screenshot
giil "https://share.icloud.com/photos/abc123"
# Image saved to current directory
# Agent can now analyze: screenshot.jpg

Exit Codes

GIIL uses specific exit codes to indicate different outcomes:

0Success - Image downloaded
10Network error - Check connectivity
11Auth required - Link not publicly shared
12Not found - Link expired or deleted
13Unsupported type - Video or document
Warning
Exit code 11 (auth required) means the link is private. Ask the user to update sharing settings to "Anyone with the link."

Advanced Usage

bash
# Download to specific directory
giil "https://share.icloud.com/photos/abc123" --output ~/debug-screenshots
# Get JSON metadata (useful for scripting)
giil "https://dropbox.com/s/xyz789/screenshot.png" --json
# Download all images from a shared album
giil "https://photos.google.com/share/album123" --all
# Check if download succeeded in a script
if giil "$URL" 2>/dev/null; then
  echo "Image ready for analysis"
else
  echo "Download failed with code $?"
fi
Note
GIIL only supports images. For videos or documents, you'll need to download them manually or use a different tool.
