HP Chromebook 14 and iPhone

I recently bought a HP Chromebook 14 for my junior year to do homework, papers, essays, etc. I also just ran out of storage on my iPhone 5c, so I would like to move some of my photos from my phone to my computer. I tried to download iTunes and iCloud but it says I need an app on my computer. I'm totally confused and I just need help moving photos from my phone to my computer.

Connect your phone to your computer and when it pops up with your phone info click "Open folder to view files." Click through the folders and before you know it, you'll be at your photos! There should be 3 different folders inside of one folder and ya it's pretty confusing but just cut and paste them from your phone onto your computer. Or just email the pics from your phone to your email and then download them again from your email on your computer.
