refactor: replace <img> tags

[JaeAeich]

Description

Using <img> could result in slower LCP and higher bandwidth. Consider using <Image /> from next/image to automatically optimize images.

Can I work on this @JaeAeich ?

Thanks @psankhe28 - looks like @anantJjain addressed it already. But please just feel free to assign yourself to any open issue that isn't assigned to anyone else - no need to ask first :)

Also, if an issue has been assigned to someone for weeks, and there is no PR - then it's okay to ask about the status. It might well be that the issue isn't actively worked on.

Okay. Thanks!
