How can add images too the members by putting their title help me..?
Do you mean like a group image?
ACP > Users & Groups > *desired group* >
Then there's an option to set a group image if I'm not mistaken.
Go to AdminCP > Users & Groups > Groups. Edit all groups you want to give a group image.
The group image is a relative path from the mybb root.
For example: images/groupimages/english/team-moderator.gif
You can change 'english' to '{lang}' to support multiple languages.
Good explanation thanks friend...
