Imagga’s Auto-tagging API is used to automatically tag all photos that are available for free download from the Unsplash website. Providing relevant tags for the photo content is one of the most important and challenging tasks for every photography site offering huge amount of image content. Imagga’s Auto-tagging API empowers the sophisticated backend system used by Unsplash to categorize photos and enhance the image metadata.
Unsplash went from 20 000 to 4 000 000 downloads a month and currently generates 350 000 000 photo views. The site is happy to have the highest engagement rate per photo compared to any other photography website.
The Challenge Unsplash experienced exponential growth of photo downloads and needed to provide a better search experience for the users of the service. Even though only 10 photos are being added per week, they needed to have all incoming image suggestions tagged and classified to ease the process of preselection.
Unsplash wanted to give its clients the freedom to do precise image search using keywords but also the opportunity to narrow down the search results by predefined categories like Nature and People, etc.
“We picked the Imagga API because it was by far the simplest and most reliable API we could find. Developing our own in-house solution would have been a wasted effort as the Imagga Tagging API has been really solid.”
The Solution Imagga API is important component of the Unsplash tagging system and is used to instantly tag all photos uploaded to the service. The initial image content as well as all new photos are parsed through the Imagga’s image tagging API to enhance the image metadata and provide powerful image search capabilities.
Imagga’s auto-tagging API is used every time somebody submits photo to the service - keywords that best describe the image are automatically suggested and the photo is being automatically categorized, giving an idea to the uploading artist under which category the photo will be visible if approved.
Unsplash developers liked the simplistic but yet powerful restful API Imagga provided.
“Implementing Imagga’s API was not hard at all. We wrote a quick Ruby wrapper around the tagging endpoint and had it integrated in a few hours.”
Results In the first month after Imagga’s Tagging API was implemented, it helped to power over 1 million searches on the Unsplash website. That number has now grown to over 5 million searches per month.
