It would be nice if Garmin Connect "picked up" the pictures I have uploaded to Flickr while I was doing an activity, and presented the images on the "Details" page of the activity here at Garmin Connect.
If I'm on out road cycling I often take a few pictures (pocket in the back pocket of the jersey), and connecting them to the activity here would be nice.
Flickr has an extensive API: http://www.flickr.com/services/api/
Hope Garmin can look into this.
Edit: This type of Flickr integration is used by another forum I use. The website if for all kinds of events (music, sports, etc) and everyone who ticks the checbox "I'm going" will automatically have their Flickr pictures from that time period displayed on the event page.
