Thanks for the replays.
Yes this is about trying to upload an image to a forum post using the browser on my phone. No Pi involved other than being the subject of the picture!
I had assumed that the file upload buttons could be used for parking the image ready to be embedded. Reading your response tells me, that was wrong . So my issue is resolved. The only way to embed an image is by using a third party site like photobucket then link to it in The post. I presume using the square brackets "img" formatting code makes the image show rather than the URL? Will give it a try. Thanks again for taking the time to help out. You both do a great job.
