Understanding Image Hosting for Websites

What Is Image Hosting for Websites?

An image hosting service allows you to upload images to a remote server for viewing online. You can then display the images to users via your website or web application, without having to allocate storage space for images on your web server. 

Image hosting services offer a user interface you can use to upload images from a local device or from cloud storage services. An important aspect of image hosting services is that they can improve website performance by delivering content to users near to their physical location.

Many image hosting services also offer an application programming interface (API) to upload and retrieve images programmatically. Some image hosting services also provide a file upload interface you can use on your website, to allow users to directly upload their own files. 

Here are a few popular image hosting services:

• Cloudinary: An image hosting service that offers advanced features for website owners to manage and optimize images on their sites. It supports large video and image files and offers a generous free plan.
• Flickr: One of the oldest and most popular free image hosting sites, with billions of photos shared in millions of groups
• Imgur: A popular image hosting site for Reddit, with an easy-to-use interface for uploading photos
• Pixabay: Offers 1.6 million royalty-free images and videos uploaded by photographers and videographers
• 500px: Primarily for showcasing images, with no links to other sites
• Unsplash: A free stock photo site with over two million photos uploaded by photographers
• SmugMug: A trusted choice for over 75 million users, with unlimited cloud storage and bandwidth
• Photobucket: A popular video and photo hosting site with a free account that includes 25 GB of monthly bandwidth and 1 GB of space

File Format Limitations

When considering an image hosting service, it’s essential to understand the file formats supported. Some platforms might have restrictions on specific image or video formats, which can affect the type of content you can host.

Image Hosting vs. Photo Sharing

Photo sharing services are very common today, and chances are you have used one via a website or smartphone application. A photo sharing service lets you create virtual photo albums and share them online with friends and family.

Another feature of a photo sharing service is that it provides storage space (many services provide a generous amount of storage for free), allowing you to move images to the photo sharing service and free up storage space on your camera, smartphone, or personal computer. Examples of photo sharing services are Google Photos, Flickr, and Amazon Photos.

Here are the key differences between photo sharing and image hosting:

• Photo sharing is limited to the platform on which the photo was uploaded. It is typically not possible to embed an image from a photo sharing site to another blog or website. Also, many photo sharing sites are limited to photos and do not support illustrations, avatars, banners, or other types of graphic files.
• Image hosting allows you to reach a larger audience. An image hosting service allows and encourages embedding of photos directly on other websites, by providing direct links to images, and other methods like code snippets that allow you to embed an image on a third-party site.

How an Image Hosting Service Works

Image hosting sites usually provide some of all of the following options for uploading files:

• An upload interface that lets you select files on your local device and upload them to the service
• The ability to upload a ZIP file and have the service automatically uncompress it and add the files to storage
• An FTP server that lets you upload files in bulk
• An API that lets you upload files programmatically
• An uploader widget that allows users to upload their own files via your website
• Upload via integration with other cloud storage services

At the end of the upload process, the image is hosted on the server. You then receive one or more of the following elements that allow you to embed the image on your website or third party sites:

• Direct link to the hosted image, which can be included in HTML via the <img> tag
• Auto-generated HTML code that displays the image
• BBcode that displays the image
• Embed code that uses JavaScript to dynamically display the image
• Clickable thumbnails that link to the full image

Image hosts often impose limits on the maximum image size allowed, the total amount of storage, the maximum bandwidth allowed per period, or some combination of these. Free services typically have a relatively small per-image size limit compared to paid services.

How to Choose an Image Hosting Platform

Performance

Hosting your images on a third-party platform can reduce load on your web server and ensure images are served faster to users around the world. To evaluate performance offered by an image hosting service, consider elements like:

• Which CDN the service provides, and whether it supports more than one CDN
• Number of points of presence (PoP), and whether there are PoPs near to your users
• Bandwidth restrictions
• Service level agreements (SLAs) the service offers for performance
• Whether performance features are only offered in premium service tiers

Storage Space

Most image hosting services provide a free plan with a limited amount of storage. Estimate how much storage you will need, and see whether a free plan will be enough for the foreseeable future. If not, consider the costs of scaling up storage on the service. Also note that some hosting services limit image quality in the free plan, and see if this is acceptable for you.

Take into account your content velocity. Consider how many images you have now, and how many you expect to add over time. If you allow users to upload their own images, storage size could grow exponentially.

Security

Most image hosting services provide robust security measures, but it’s important to check the specific security features offered by each service. If your organization and the images you store are subject to compliance standards (such as GDPR or HIPAA), make sure the image hosting service supports that standard.

Another important aspect is to understand what you need to do to secure your data. Hosting services provide security features such as setting permissions for images, but they do not configure them for you. It is your responsibility to define secure configuration for your images to meet your security and compliance requirements.

Easy of Uploading Photos

When choosing an image hosting platform, consider how easy it is to upload photos. Some platforms might offer drag-and-drop features, batch uploads, or integrations with other tools and services. The smoother the upload process, the better the user experience.

Direct Linking and Other Features

Direct linking allows you to share the direct URL of an image, making it easier to embed or share on other platforms. Additionally, some image hosting services might offer features like image galleries, HTML links, editing tools, and privacy options. These features can enhance the functionality and versatility of the hosting service.

Easy of Use

Prefer an image hosting service with an intuitive user interface. There should be an easy way to upload files and manage existing files in your image archive, and it should be simple to define service settings.

In addition, a good image hosting service also provides developer tools that can let you integrate it with your internal systems. See if the service offers an API, if it supports the development language used by your website, and whether your developers are comfortable using it.
