This page gives an overview of the terms used in PicApport

Add-on Add-ons are scripts created in the programming language Groovy which extend the functionality of the PicApport Server. For further details see: PicApport Add-on Guide
Dynamic Collection 

Dynamic collections are queries stored on the PicApport server. If new photos matching the query criteria have been added to the server since the last execution of a dynamic query, the query result will also change.

The visibility (regarding users or groups) can be specified when saving a dynamic collection.

  • Geolocations
  • Geo-Coordinates
This generally refers to the possibility of recording the location (coordinates) of a photo directly in the metadata of the jpg file in order to be able to display it on a map in PicApport. The coordinates can be created automatically by the camera when the photo is taken and later with the map function of PicApport. See also the tutorial video:
GeoJSON file format 

GeoJSON is an open format to store geographical data of e.g. travel routes or maps. PicApport is able to display these files in the integrated map module and since version 9 it is also able to generate them.

If a user is authorized to do so, it is possible to like a photo.

Likes of different users are counted for each photo and can be queried with the ++ and operators.

Local collection 

Especially on a cell phone it is very useful to be able to show photos even if you have no connection to the PicApport server. The „Local Collections“ serve this purpose.

If the browser supports the IndexedDB technology, it is possible to save even several thousand photos in the browser of the cell phone without having to install additional apps. This is possible because PicAppport scales the photos to the required display size before sending them to the device.

Since „Local Collections“ are also based on stored queries, new photos matching the query can be automatically loaded to the phone via a synchronization function.


Metadata of digital photos are, for example, date of shooting, camera model, location, etc. See also:

Thumbnail view
  • Thumbnails
  • Thumbs

The thumbnail view shows an overview of all queried photos as „thumbnails“.

  • Sharing photos
  • Edit Metadata
  • Marking photos
  • Show metadata details
  • etc.

  • My tags

MyTags gives authorized PicApport users the possibility to add their own keywords to photos and search for them with their own operator (#).

Unlike tags and keywords, MyTags keywords are not stored in the photo file itself, but in a file on the server that is managed separately for each user.

  • Search operators
  • Search functions
Operators are special functions to find photos in PicApport. See also: Full text search of photos – Supported metadata
