Thanks rolf :D
I figured that out.. got my key... and it is doable.. read/found the thing to do it ..
http://www.flickr.com/services/api/flickr.photos.search.html
among the optional parameters i found those in flickr.photos.search :
min_upload_date (Optional)
Minimum upload date. Photos with an upload date greater than or equal to this value will be returned. The date should be in the form of a unix timestamp.
max_upload_date (Optional)
Maximum upload date. Photos with an upload date less than or equal to this value will be returned. The date should be in the form of a unix timestamp.
group_id (Optional)
The id of a group who's pool to search. If specified, only matching photos posted to the group's pool will be returned.
it seems easy... something out there must have been done :P ! any good flickr plugin website anyone knows about ?
-- yeah i know i am super lazy... i just don't wanna re-invent the wheel !
thanks rolf !
