There have been several recent (and not so recent) improvements in Picasa web service that Google owns, making it serious challenger to Flickr, which I have long used. (See a list from here.) There is also a cost issue: the Pro account of Flickr is $25 per year (unlimited uploads, unlimited storage), but you can get 20 GB of disk space from Google/Picasa with $5 per year. Rather than cost, it is really the privacy controls that start to concern me more and more as the kids grow up. Picasa web albums makes it a bit easier to share private photo albums (you just enter email addresses and send the invitation link). This, and other reasons have led me to consider migrating my photo galleries from Flickr to Picasa. As I have several deep integrations set up (particularly all photos in this blog actually reside in Flickr), it is questionable whether this transition really makes sense. On the other hand, I hate being tied to any single service, without ability to change service provider when needed. Flickr has not been particularly dynamic in coming up with new functionalities recently. Yet, integration with my mobile camera phones and mail systems is something that works well with Flickr, and I am not sure how such things would appear under Picasa/Google. But we will see. I am using the holiday period to do some tests, experimenting first with the free Migratr tool to backup and transfer all my Flickr photos into the Picasa account. It appears a bit buggy/easy to crash, but lets hope for the best. It is interesting to see how the transfer works out, and having backups in several places is a good idea in any case.
