I use a program (app) on my computer called image resizer. The app is available free in the Microsoft store. I take a photo, put it in a file, go to the app, hit open and find the right folder and photo in that folder. There is a slide-bar that takes the photo down by percentage. At the right percentage I hit save and rename it. With my android phone I have to reduce my photos to about 15% to achieve 180 KB or smaller. It becomes easy after doing it a few times. Its a pain, but has to be done or the photo will not post, as you know.
