Whether to include a photo on a CV is a matter of personal preference and varies by country. In some countries, such as the United Kingdom, the United States, and Canada, it is common not to include a photo. However, in other countries, such as France, Germany, and many European countries, including a photo is the norm.

If you choose to include a photo, it's important to make sure that it is professional and appropriate. It should be a recent, clear headshot, and you should dress in business attire. The photo should also be a good representation of how you look on a typical workday.

Ultimately, the most important thing is to ensure that your CV is well-written, concise, and focuses on your skills and experience. If including a photo would detract from the content of your CV, it's best to leave it out.
