How to display block with term image field when viewing term node I'm using the default Taxonomy term view in drupal 7.
I have Vocabulary: Portfolio with terms: Wedding Photos, Kids Photos, Other Photos. And I want to show a block of the term image field when a specific term is visited.

similar to this ( Add taxonomy term image to a view ) 

But because there are many content types in the same category the block is showing many term image fields instead of just one.
I try different Contextual filters and Relationships and Query settings: Distinct. But no result so far.
I found my error: In the Format: Settings I had Grouping field N1 selected with the category term image field, which caused the duplication of the image.

Contextual Filters: Content has taxonomy term ID (with depth), Depth:0, Provide Default Value: Taxonomy term ID from URL > Load default filter from term page
Relationships: Entity Reference: VocabularyName - Require this relationship
Fields: Taxonomy Term - the term image field - using Views Distinct I select Filter Repeats
