First, you must understand why images are so important to your website's performance. The truth is, images are among the most important parts of a web page: they represent your content, act as buttons and links, display animation and interact with the rest of the site. A poorly-designed web page can lose customers, lose search engine rankings, and even get you banned from certain sites - all because it used image sizes or dimensions which aren't recommended. That's why optimizing images for the website can be a big help, and it can help you avoid common mistakes and potential headaches down the line.

First of all, you have to know what size and type of images will look the best when displayed in your website. Keep in mind that different images tend to occupy different areas of a page - for example, an image that's located in the top right corner will likely get smaller as you scroll down the page, while an image in the upper left corner of the page will likely get larger as you scroll further right. As such, you have to be aware of these differences and choose images accordingly. If you don't, you'll be stuck with images that either won't load properly or that look stretched out of proportions.

Image scaling is an option, but it's one that you should really consider before you even try to resize your images. Even if you're not going to change the actual size of the images, changing the aspect ratio of the website will drastically affect the final image's size. This means that if you have images that are too small for your current display size, then you should definitely consider taking them down until you can fit more onto the site. Scaling the images also ensures that the final images will be viewed in their most appropriate proportions.
