The new version of Flickr for iOS bringss the photo-sharing app a little more in line with similar social apps Instagram and Twitter. Now, when you take a no filter, beach picture in the middle of summer, you can post it on Flickr’s iOS app as a #nofilter picture of the #beach in #summer.

Yep, Flickr for iOS now has hashtag support. You can addd hashtags to any photo’s title of description, and like hashtag functionality in any other app, clicking on the tag will open up a search of other photos on the service with the same hashtag.

Version 2.11.820 also allows iOS users to participate in Flickr’s weekly photo challenge, #FlickrFriday.

You still won’t find any “hashtags” on Flickr on the web – it’s still just “tags.” And any current web tags don’t translate to clickable hashtags on the iOS app. It look like for now, this shift toward hashtags is a mobile-only venture for Flickr.

In other hashtag news, anyone popular social service may be adding them in the near future. Recent reports said that Facebook is working on incorporating the hashtag.
