Is it possible to search for certain pictures within the 'Pictures' folder? If not, it should be implemented, it would make things a lot more efficient. ( I have tried searching, but the keyboard doesn't respond when i'm in the 'Pictures' folder. )
You can't search from the photo app. You need to do it through the main search in the home screen or use the file manager. Also, unless you rename the photos, it's not going to find them. You can use a usb cable and manually rename them in windows or add the photos on folders with labels. You may also be able to tag multiple photos with programs for pics, but that still requires work.
It could add places according to the exif tags in the pictures and detect faces automatically (like the Nokia N9). Or it could add the option to automatically rename or tag the photos if a calendar event is running or if BlackBerry Travel knows that one is on vacation.
