Bernard, you apparently did everything correctly, but probably did not click on "Done Adding File" in the file manager after you got the file name to appear above the window. Do not click on the "x" to close the file manager window manually. It's important to WAIT for it to close on it's own (which it will do once "done adding files").
Carl I could not get the file name in the window.I followed Hung's instructions to browse then my pictures came up and I selected one but could not get it to the forum post.
You did it once at least, Bernie! The file name you selected appears in your post above, but the link isn't complete. That usually happens when you forget to click "Done Adding Files".
Try it again. It worked before! All you have to do is complete the correct sequence.
Click on "File Manager". The file manager screen appears.
Click "Browse" and the browser screen appears. Find your file.
Click on (or double click on, if needed) the file you want to load. The browser screen disappears and the file you selected now appears in the file manager's window.
Click on "Add File". Important: wait for the filename to move to above the window indicating the file was uploaded!
Click on "Done Adding Files" to complete the process, and the file manager disappears so you can complete your posting.
