[iPhone disabled, connect to iTunes] can I save my pictures?

So a couple of days ago, my phone was acting pretty slow, so I decided to power it off and then turn it back on again (I’ve done this before many times and nothing bad had ever happened) and when I turned my phone back on all the screen said was : iPhone disabled, connect to iTunes. I didn’t type in my password wrong or anything, it just went straight to disabled. When I tried connecting my phone to iTunes, my device wasn’t recognized. I also hadn't backed up my phone to iCloud in over 2 years, as I had the lowest default amount of storage(after this whole thing though, I upgraded, and photos from my other devices have successfully uploaded to the cloud). Could the photos I had on my phone be uploaded to the cloud even when it’s disabled? Now that I have all of this new storage would my disabled phone recognized that or is everything just completely frozen? Or is there any way the phone could be taken apart and data saved that way? I don’t care so much about the rest of the stuff I had on my phone, but my photos really mean everything to me and I’m willing to do whatever it takes and spend however much money I need to in order to recover these , if possible. I also should add that I went to the apple store already with these same questions, and the person I spoke to didn’t really seem to know much of anything about what I was asking. Any help at all would be very much appreciated!!
