Taking the time to download many images from a website can be quite tedious. Right click, Save Image As again and again.
It is now possible to work with images using a variety of applications that are available today. In order to be able to create the one for any purpose, for example, for image retouching, colorizing, or any other purpose, you need pictures and consequently, obtain the URL of an image on a website to scrape for every photograph you use.
However, the task may prove a challenge for you, since sites like Facebook and Flickr, for instance, provide a URL to a photo that turns out to actually be a link to a whole album of photos rather than the actual file itself. Whenever it is necessary to pull images from a website, web scraping can be a great solution. A number of ways can be used to accomplish this. It is well known that there are numerous options for data delivery such as off-the-shelf options, custom web-scraping tools, or even turning to professional data delivery services, such as ProxyCrawl.
If you are experiencing any of these problems, web scraping can be your solution. This tutorial will explain how to use a free web scraper to extract the URL for every image on a webpage using the technique called web scraping. Additionally, we will describe how to use this extracted list to quickly download all the images to your computer, by using the extracted data.
Scraping with ProxyCrawl
This easy task will require you to use a web scraper that can take the URLs in question and automatically extract the necessary information. Using ProxyCrawl, an incredibly powerful web scraper that is completely free, is the perfect choice for this type of project.
5 Methods Of Scraping Image From Web Pages
We will assume that this is an example of what we are looking for, that is, to download every image that appears on the first five pages of results on Amazon.ca for “wireless earbuds”. There is potential for this information to be extremely valuable for analyzing competitors.
1. Get Started
- Once you have downloaded and installed ProxyCrawl on your computer, you will need to ensure it is up and running.
- Make sure you know what URL we will be scraping from the specific page we will be scraping.
2. Setting up a Project
- We will be scraping the Amazon website that we will be using in ProxyCrawl, so click on “New Project” on the tool bar.
- You will be able to choose which images to scrape from the webpage once it renders in ProxyCrawl, and then you can scrape the content.
3. Select the images you want to scrape
- In order to start, you need to choose the first image that appears in the search results. This will then turn green to show that it has been chosen to be scraped.
- When you click on the another button, all of the other images in the search results page will appear yellow. By clicking on the second image, all of the images in the search results page will be highlighted in yellow. All of the buttons will turn green, indicating that they have been selected for extraction.
- Due to the fact that these images also serve as links to the product pages, ProxyCrawl is pulling both the image URL as well as the link it is pointing to (the product page). We will, therefore, be removing the selection of URLs from the left sidebar of the page and only keeping the links for the images.
- In order to scrape every image URL for the first page of results, ProxyCrawl has now been modified to scrape every URL.
4. Pagination
ProxyCrawl can now be instructed to extract the same information for the next five pages of search results by instructing it to do so.
- By clicking on the PLUS(+) sign to the left of the selection of a page, you will be able to use the command of selecting a page.
- Next, select the “Next” button and scroll to the bottom of the search results page to see the result.
- If the next button is clicked, the link will be extracted by ProxyCrawl by default. In order to remove the two items under the “Next” selection, we will click the icon next to it and uncheck the two items.
- Once we have selected “next”, we will be using the “click” command to activate the PLUS(+) sign next to “next”.
- A window will pop up asking if this is a Next Page link. In order to repeat this cycle, you need to click “Yes” and enter the number of times you wish this to happen. For this example, we will do it 5 times.
5. Scrape and Export Data
Next, we will let ProxyCrawl run and retrieve a list of URLs for each image selected previously.
- You can get the data by clicking on the “Get Data” button on the left sidebar.
- It is important to note that the following section allows you to choose when to run the scraper. Despite the fact that it is always advisable that you make a test scrape before running a full scrape, we will run a sample scrape for our example right now.
- Using ProxyCrawl, you will now be able to scrape the image URLs you have selected. You have the option of waiting on this screen or leaving ProxyCrawl. Once your scrape has been completed, you will be notified. In this case, it took less than one minute for the process to be completed.
- Click on the CSV/Excel button once your data is ready to be downloaded. Once you have saved your file, you can rename it as you wish.
Images downloaded to your device
As soon as we have a list of all the URLs for each and every image in our hands, we will be able to download them with the same simple tool on any device we have.
In order to achieve this, we will use the Chrome extension Tab Save.
Upon installing the extension, you will be able to open it by clicking on its icon. To enter the URLs, click the edit button at the bottom left of the extension after clicking the button below. You can download all images automatically by clicking the download icon in the extension window. If you are downloading a large number of images, it may take a few seconds to download them all.
