The android app "A Photo Manager" can use TAG-s as a powerful tool to find and group photos in a gallery view.

Example: Show all photos of peter at a harbour at night.

peter, harbour, night (and other words you choose) are TAGS that can be attached to photos.

Keywords, Categories, Searchterms, Descriptionelements or Virtual-Albums are synonyms for TAG-s.

The TAG-s are grouped in hirachies to make it easier to find TAG-s that belong together.

Example

• In the TAG dialog search for "peter"
• The list displays "/people/family/peter"
• If you short-tap on the "+" button only "peter" is added to the added TAG-s
• If you long-tap on the "+" button "people", "family" and "peter" are added to to the TAG-s
• with one search you get three tags which is usefull if you have many potential tags.

The TAG Dialog is used in these Scenarios:

• Usage: How to use/find/mark/add/delete Tagnames
• Find/Filter: Example: I want to see photos of peter at a harbour at night
• Edit Photo Properties (exif): Example: In Selected Photos add TAG-s peter, harbour, night and remove TAG "winter"

• The main part of the dialog is the List of TAG-s.
• The TAG-s are organized and displayed similar to file-paths:
  • Example: TAG "Holiday" contains the subtags "Beach", "Excursion" and "Habour".
  • Example: the TAG "Habour" is displayed as ".../Holiday/Habour" because it is below parent TAG "Holiday".
• If you long-tap on a tagname you get a context-menu:
  • Create new TAG to add new childtag below the tapped parent TAG.
    • Note you can add more than one child TAG if you seperate them with ","
      • Example: if you long tap on "Holiday" and enter "Beach,Excursion,Habour" you will add three subtags below "Holiday".
    • Note you can add a TAG path by using path seperator "/"
      • Example: if you long tap on "People" and enter "Family/Peter" you will add "Family" to "People" and "Peter" to "Family.
      • Example: if you long tap on "Holiday" and enter "/People/Family/Peter" you will create root category "People", add "Family" to "People" and "Peter" to "Family. Note the preceeding "/" before "People"
  • Rename rename the Text of the selected TAG.
    • optionally you can choose if you want tho change the TAG-s in the affected photos, too.
    • Note you can modify the TAG hirarchy via rename:
      • Example: Rename "Peter" to "Family/Peter" will insert a new hirarchy element.
      • Example: Rename "Peter" to "/People/Peter" will move "Peter" directly below "People".
  • Delete delete the selected TAG.
    • optionally you can choose if you want to delte the child-TAG-s, too.
    • optionally you can choose if you want tho remove the TAG from the affected photos, too.
  • Cut cut selected TAG with sub-TAG-s to clipboard
  • Copy copy selected TAG with sub-TAG-s to clipboard
  • (Paste) After cut or copy you can paste the TAG-s with sub-TAG-s below selected TAG.
• In front of the TAG-path are marker buttons
  • If you tap on a marker button you toggle the marker between on and off
    • If you long tap on a marker button the item and it-s parent items are selected.
      • Example: If you long tap on bookmark "/_demo/holiday/habour" then the TAG-s "_demo", "holiday" and "habour" are bookmarked.
• or "Ok" button apply the changes.
• or "Cancel" button or the back button closes the the view without applying the changes.

The List shows TAG-s that

• match the incremental search edit field (in the example: contain "bea") or

• that is bookmarked with or

• that is marked with add or remove or

• that is already included in at least one of the selected photos

• In incremental search mode there is incremental search edit field: TAG-s that match are shown

• In bookmark mode the incremental search and it-s result are hidden.

• You can toggle between and by tapping them.

In "A Photo Manager" you can find photos via TAG-s through

• the TAG-s-[...] button in the Filter-View
• the TAG Filter menu or symbol in Gallery-View in non multiselection mode.

In Filtermode the checkmarks in the TAG list have this meaning

• Images must contain all TAG-s that are marked with .
• Images must not contain any TAG-s marked with
  • Example: if you mark the TAG-s peter, harbour, night with and the TAG "winter" with then you will get all pictures of peter at a harbour at night that are not related to "winter".
• TAG-s bookmarked with will not be removed by the search filter

In "A Photo Manager" you can add/remove TAG-s of one or more (selected) photos through

• the Set TAG-s menu or symbol in Gallery-View in multiselection mode.
• the Set TAG-s menu or symbol in Image-View.

In photo-tagging mode the checkmarks in the TAG list have this meaning

• TAG-s that are marked with will be added to the selected images.
• TAG-s that are marked with will be removed from the selected images.
• TAG-s bookmarked with will not be removed by the search filter
