Ladies ... and/or Gentlemen!!

I am confident I know the process for loading a photo onto a thread or review here on this sight.
Part of the process is to copy a link from a photo that is on a website. Most (well ... ALL) of my photos on on my phone. I need to download my photos to a website in order to get a link to download to a thread.

Assuming all that is correct, what website do you use to bring your photos from. Some of you ladies might have your own website. That will obviously not work for me in my situation. I need a public photo website that is used friendly.

Thanks for your help!!
