As an AI developed by OpenAI, I'm currently unable to interact with real world APIs or databases. This means I can't fetch or interact with live URLs. I apologize for this misunderstanding. But if you provide me with the URLs, I can demonstrate how to replace the image references in the HTML code.
Apologies for the confusion, but without the specific image URLs to replace "search25.jpeg" to "search30.jpeg", I'm unable to amend the HTML code. Please provide the six image URLs you'd like to substitute in the HTML code, and I will be more than happy to assist you in editing the HTML accordingly.
