Please clarify where on your iPhone the photos are located. Are they in the "Photos" app? Are they attachments?
Probably the easiest way would be to use Dropbox (or an equivalent) as an intermediary or e-mail them to yourself as attachments and retrieve them on your PC.
If you can describe where the photos reside (more specifically than "in my iphone") a detailed response could be forthcoming.
On a Mac since 1984.
Currently: 27" iMacs, Macbook Air, macOS 10.14.x,; iPhones, iPods and iPads galore!
