- Developers build datasets for training machine learning models in tasks like image recognition or classification.
What data can be scraped from Google Images?
When scraping data from Google Images, you can extract several key pieces of information associated with each image:
- Image URLs. Direct links to the images, allowing you to access and download them for your projects.
- Source page URLs. Links to the web pages where the images are originally hosted, providing context and additional details.
- Titles & descriptions. Text describing the images or their source pages, helping you understand the content and relevance.
- Domains. The websites that host the images, useful for categorizing sources or assessing credibility.
- Positions. The rank or order of the images in the Google search results, indicating their relevance to your search query.
- Search information. Metadata about your search query, including the exact terms used and any corrections or suggestions provided by Google.
By collecting this data, you can effectively utilize the images and their associated information for various purposes, such as building datasets for machine learning, conducting research, enhancing content, or analyzing trends.
5 methods for scraping Google Images
Scraping Google Images can be accomplished through various methods, each suitable for different needs and levels of technical expertise. In this section, we’ll explore how to scrape images from Google using some common approaches.
1. Google’s official API
Google offers an official API for extracting image content called the Custom Search JSON API. This API allows developers to retrieve and display search results from Google Custom Search programmatically. Specifically, it supports image searches, enabling you to obtain image URLs, thumbnails, and associated metadata directly from Google in a structured JSON format. Unfortunately, Google puts strict usage limits and associated costs, which can be restrictive.
2. Requests and BeautifulSoup libraries
Python's requests library allows you to send HTTP requests to web pages, while BeautifulSoup helps parse and navigate the HTML content. By combining these libraries, you can write a script to search Google Images and extract data such as image URLs, titles, and descriptions. This method gives you control over the scraping process but requires handling Google’s anti-scraping measures. For a detailed guide, refer to our Python tutorial on scraping images from websites.
3. Automation with Selenium
Selenium is a powerful tool that automates web browsers, making it ideal for scraping dynamic websites that rely heavily on JavaScript. With Selenium, you can simulate user interactions like scrolling and clicking, which is useful for loading more results on Google Images. This method can handle complex scraping tasks but may require more computational resources and coding expertise. To learn more about this method, check out our blog post on scraping the web with Selenium.
4. Employing the google_images_download library
The google_images_download Python library is designed to download images from Google Images. It simplifies the process by allowing you to specify search parameters, the number of images to download, and the desired image format. This user-friendly tool requires minimal coding, making it accessible to those less experienced with web scraping.
5. Dedicated Google Images scraper
For a more efficient and hassle-free solution, you can use a dedicated scraper like Smartproxy’s SERP Scraping API. This API is designed to simplify the data-gathering process from search engine results pages, including Google Images. It handles all the complexities, such as rotating proxies, CAPTCHA solving, and parsing the data into a structured format. This means you don't have to worry about technical challenges or extensive coding.
We even offer a ready-made scraper that can scrape images from Google and doesn't require much or any coding experience. With our SERP Scraping API, you can quickly and reliably collect the image data you need for your projects.
Scraping Google Images with Smartproxy’s SERP Scraping API
Let’s say we want to train a machine on what human hands look like. For that, we'll need a large dataset of hand images that capture various positions, angles, skin tones, and lighting conditions. Collecting thousands of such images manually would take too long, so we’ll use an automated web scraping tool called SERP Scraping API.
1. Get SERP Scraping API
Log in to your Smartproxy dashboard, navigate to the SERP tab under the Scraping APIs column on the left panel, and choose a subscription plan or claim a 7-day free trial to test our service.
2. Find the ready-made scraper
A ready-made scraper is a pre-configured template within our Scraping API that offers target-specific scraping with appropriate parameter options and parsing capabilities. To find the Google Images ready-made scraper, follow these steps:
- Access the Scrapers tab.
- Choose to Create new scraper or look at the list of Popular Scrapers below.
- Click on google_search.
- Expand the Target specific menu and, for the TBM (term by method) option, choose Google Images - isch.
You now have the scraper set to target Google Images!
3. Configure your scraping request
Enter your query (search phrase), parameters like language, location, device type, browser, and website domain, as well as pagination and other specifications. If you enable the Bulk parameter, you can target several queries simultaneously.
In our case, since we’re collecting images of hands, we’ll enter "hands" as our query.
4. Send your request and export the response
Once you’ve set up your scraping parameters, click the Start scraping button or opt for the Schedule button to execute your project and have the response delivered to your email address, webhook, or Google Drive at intervals that suit you – hourly, daily, weekly, monthly, or a custom rate.
Alternatively, you can copy the request code in cURL, Node.js, or Python and integrate it into your development environment. Check our documentation to adjust the parameters to suit your needs. Our request code in Python looks like this:
import requestsurl = "https://scraper-api.smartproxy.com/v2/scrape"payload = {"target": "google_search","query": "hand","locale": "en-us","geo": "United States","device_type": "desktop_chrome","domain": "com","page_from": "1","num_pages": "10","google_results_language": "en","google_tbm": "isch","parse": True,"google_safe_search": True}headers = {"accept": "application/json","content-type": "application/json","authorization": "Basic [BASE64_ENCODED_CREDENTIALS]"}response = requests.post(url, json=payload, headers=headers)print(response.text)
After clicking Start scraping, you’ll receive the response in JSON or table format shortly. You can copy this data or export it in JSON or CSV format.
Great job! We now have a large dataset of images that we can use to train our machine learning model or for any other project you have in mind.
