I don't know the technical background, but I learned you have to give a url for your image so you have to upload it into some image management facility which provides a web link to it. I use Photobucket (because someone told me it was good, not because I researched and compared it to others). Once you upload the photo into that facility, it gives you a link to use for that photo. I also use Steemstyle to see what it looks like before posting. Hope this helps.
I'm glad you liked it, @stbrians. Wish I knew the answer to your question, but I have no idea why your smartphone would not upload photos...😞
I do not figure where the problem is in fixing images in my steemit posts. Maybe am just dumb and deft
