Images in posts

a png
The bbCode looks like:

Some tags for: #photo #foto #images
The tags are written as:
≠photo ≠foto ≠image ≠images
(here ≠ instead of hash, how to escape?)
3 months ago But when edit the post and removing the textual tag ≠image, that tag is vanished from the text and from the tags link line.
I can read the post, but do not see the image. Clicking on the placeholder imgage tell notification no permission.
Im not able to correct (edit) the spelling mistake of my previous comment.
