Scraping Images from Web Pages

Web scraping refers to the process where a software extracts contents from a web source and then converts them into a more organized set of data. This technique is used mainly for downloading important information from a website. It can also be used to track changes in a website, to monitor product prices, or to scrape images from web page.

Why You Need to Scrape Images

There are a number of reasons to scrape images from web page including the need to compile a set of images that come from a single source. For example, an online magazine commonly releases new covers every month. If you need to compile all the covers that magazine has released from the very first cover, web scraping is a great option.

Another example is when you need to collect all the pictures of a certain artist’s public artworks. The classic method of right-clicking the picture and selecting “save as” may do the work. But such method can consume a large portion of your time especially when you need to save upwards of a hundred images. It will definitely be a time-saver if you scrape images from web page instead of saving each of them manually.
