Absolutely you can.
Coding is mainly reserved these days for people who require a specific type of complex site.  This does not apply to most people.  Therefore adding a front-end editor to your site will allow you to make the simple changes you would like and you also get training at handover.

All websites come with a basic handover and editing tutorial.
For start-up websites, any further training is not included however for the custom-built website you can receive up to 5 training videos.

Depending on the complexity of your website, in most cases, users are fairly confident after handover.
However, there are some types of websites that are more complex than others but you can book further training with me.

Changing images is covered in your handover training.

Of course, the beauty of websites is that they can grow with you.
