Images appears as post/page and Getting Indexed on Google

Hello,

I am facing weird issue with my site.

I noticed that uploaded images mostly in galleries are turning into a post or page.

For example, I have a photo named “mac” now I am getting it as https://www.itechfever.com/mac
and it is being indexed in google as well.

I have WordPress plugin to create alt text from the title plugin is “SEO friendly Images”

I checked on Google as site:itechfever.com and found the most of images has turned into a post with a URL.

How can I fix it?

For reference here, I have uploaded the screenshots –
