As silly as this question may seem, this is something that any web designer or developer can do. Yet, for the inexperienced, this can be a little more challenging. Developers write everything that you want in a website in web developing code. But, we are not going to talk about that in too much detail. If it interests you to learn the skills to do this, you can refer to this this article.
When talking about images you must first identify the type of image you are trying to add. Is it a logo, a graphic design, or a photo? Where will you locate them and for what purpose? Images are an amazing feature to add to a website for many reasons, such as:
Yet, all these purposes need a different approach, but we will get back to this shortly.
Web designers know that using images increases the website's appeal and reduces cognitive friction. You must know, most people are 90% visual and 10% textual beings. Our brains were designed to process shapes and color long before we learned to read and write.

Separating your own personal preferences at the time to choose the image will be hard. Consider the following when choosing an image:
Images come in different sizes and they rarely display on your website in their natural size. Your web designer will alter your image according to the location, size, and use. This includes cropping and sizing. One of the most common mistakes I have come across is that the photographer zoomed into the object of focus. This causes the image to cut the object of focus when it displays on a widescreen. See below the difference between a bad photo and a good photo.
As you can see above, the image was shot in portrait and the elephant was zoomed in. This would make a great poster on an office or wall, but unfortunately, it will not be as effective for web design.
The photo below was shot in landscape and the elephant was in the center. The photographer left enough environments around the elephant to allow for cropping. Because it is displayed in a wide arrangement, it fits perfectly. If it needed to be cropped to show it in a small container, there is ample room to crop the photo.
