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 images 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/*

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.
