A typical web page consists of many components that act as a medium for attracting the attention of the visitors to your website. From all the components that make a website, images play a vital role in creating visibility for your website over the web. They increase the readability of your content by splitting the long chunks of content and sharing it across the web. However, along with being beneficial in many ways images also come with their downsides.
Adding images will increase the size of your web page. A web page that is rich in images will increase its load time as the visitors will have to download them via your server to their device. This can lead to a delay in load times that will frustrate your visitors and in return have a negative effect on the rankings of your website in the search engine results.
Adding Images to Your WebPage
For uploading images on your website there are several image formats like JPEG, PNG, BMP and GIF. Specific codes are written that enables the image to be uploaded on the website. Some custom codes are also written for the images that are uploaded via the URL on the internet. Naming conventions need to be kept in mind while naming them and they must be stored in the direct directory. The name of the images should not contain any kind of symbols or alphanumeric characters.
Below are some of the ways of optimizing the images on your webpage.
Selecting the Right File Format
There are different image file formats and most commonly used ones are .jpeg, .png and .gif. These file formats are added as a suffix to the name of the image. Each file format has its own behavior and has an impact on its load time and visual appearance. So, it becomes necessary to decide the best file format for an image by analyzing the aspects like color, size and the depth of information. JPG is an image file format that displays high image quality at a reduced size. Thus, it is better to use this format where it is supported.
Setting the Image Quality
High-quality images enhance the visual aspect of a website but they will take a significant amount of time for loading as compared to the standard or low quality images. So, it is better to avoid using high resolution images as it will enable you to increase the load time of your website. Using images that have an acceptable and good viewing capability will be a good option. This will not hamper the overall design quality of your website.
Dimensions of Your Image
Every image you add to your website will take a specific amount of space. The dimensions of your image will largely depend on the layout that you have chosen for your website. Selecting the right dimensions for your images will improve the overall look of your website. Inserting images just for the sake of it will unnecessarily occupy the unwanted space that you could have utilized for the addition of some relevant content on your website.
Static and Dynamic Images
Most of the web browsers store cache locally that avoids them to re-fetch an image that has already been fetched. A browser checks the time stamp on the file and compares it with the latest version that has been fetched and stored locally. In case the file on the server is older than the available file, it won’t re-fetch the file.
The images are generated using a PHP script and there is no need to create images using the same data every time the graph script is called. Selecting a pre-stored image in the gallery and calling the same graph script will return a new image. PHP scripts enable the creation of dynamic images that produce different images that depend on some of the specified parameters with the same script name.
Dynamic images are produced by a script which will always remain the same even though the produced image is always changing. The browser will not re-fetch the images as the script remains the same.
In the End
Above post along with discussing the importance of images in a website showcases the steps you need to follow in order to add and optimize images on your website. Images have always been a pivotal part of every webpage and they always will be. So, it is important to make use of them in a very productive manner that will have a positive impact on your website.
