One more try for an image from the local drive.
PREVIEW does not show image attached from local drive.
In fact if you use preview, the path to the file goes away. You have to again use the BROWSE button and select the file before submitting the post. ( The path to the file must be showing in browse before you click on SUBMIT.)
Once you have posted an attached image file, the EDIT function will allow you to REMOVE or REPLACE the file.
