the closest way to the iphone icloud would be to use google photos
another way is to just plug the phone into the computer by usb
it will then show up as a device under my computer
double click on that and you might have to browse a few folders but its not too hard to find the folder with your pictures and just copy them with a copy and paste.
if you only need a few photos an even easier way to do it is to email or text them to your own email address. then just open the email on the computer
if you pull up a picture in the gallery on the phone there will be a forward / share button on top of the photo click that and select either email or text it looks like > with balls at the 3 points
in either the email or the text you can just put your own email address as the recipient
or you can open gmail on the phone and create an email to yourself and then attach those photos that you need.
