how to upload images on mobile

go to https://imgbb.com/ and upload your image. 

after its uploaded, it will give you the option for embed codes, copy the entire code. it should look like this.

once youre on your bulletin/blog, press the embed icon at the top. 

paste the code into it. you can remove the <a href="https://ibb.co/hRQq5hj"> if you do not want it to link to the imgbb website. once you click off the embed icon, your image should appear. 

PS- you remove any of the code as long as if still says <img src=" at the start, and " /> at the end.
