Fickree provides an editor button for simple flickr queries, but feel free to manually add short code attributes for more complex requirements (All flickr API method-specific arguments are available)
Control your own markup with mustache-based templating (Comes with 4 templates out of the box – attributed, caption, default and thick box).
Standardises: 
a) The properties available for each photo regardless of method used 
b) The arguments available for each query (including convenience arguments “size” and “display”)
Templates can include all of the data flickr returns for photos including:
id, owner, server, title, ispublic, description, dateupload, lastupdate, latitude, tags and many many more!
Queries can include any of flickr method attributes as arguments, (all extras are included by default) such as:
‘privacy_filter’, ‘text’, ‘min_upload_date’,’sort’, ‘safe_search’, ‘place_id’, ‘geo_context’ and many many more!
