The Creative Commons website has examples of best practice for acknowledgment (with more detail on the Creative Commons wiki), and suggests acknowledging this image like this:
Creative Commons a vessel ideas by opensource.com is licensed under CC BY SA 2.0
It's important if you are using any CC licensed material that you comply with the creator's terms of use, this style of reference (or similar) is ideal because it provides links to the artwork, the photographer's profile page on Flickr (or the creator's personal website) and the licence terms. The viewer has all the information necessary to enable them to reuse the image. You could also state the website the material is taken from, as has been done in the image credits of this guide.
We would also suggest (certainly for academic work) to provide the date the material was accessed at the end, as this acts as an assurance that the webpage existed if it should disappear:
Creative Commons a vessel ideas by opensource.com is licensed under CC BY SA 2.0 (Accessed 26.05.2023)
If you have adapted or edited the original work, you need to acknowledge this: "This work [your title] is a derivative of [original Title] by Author and Source used under Licence. [Your title] is licenced under [specific Creative Commons licence] by [your name]".
If you have used material under one of the 'ShareAlike' licences, you must make your work available for users to use under the same licence.

What is the difference between copyright infringement and plagiarism?
Copyright infringement takes place if you reference the third-party content used but you either don't have copyright permission, your use is not covered under a licence, or a copyright exception, or the content is not in the public domain.
Plagiarism takes place when you re-use third-party content legally but do not provide any acknowledgement of the source. Creative Commons licences are designed to ensure that you must attribute the original author/creator but plagiarism is not within their scope. See their website for their FAQs which describe in more information the difference.
