If you want to get your photos off the phone's SD card onto your computer, you can put the SD card into a card reader attached to your computer and use the computer's file browser (Mac Finder or Windows File Explorer) to copy the files to your computer.

I've yet to find an Android phone that doesn't support that. Every phone I've owned or tried to connect external storage to has worked.
