I had the pleasure of meeting Loïc Le Meur at Joi's dinner and we got together last night as well.
Loïc (pronounced Loh-eeck) is one of those 'serial entreprenuers' who hits the ground running. Doc described him as the Robbespierre of French blogging. Despite years of being told so, American software companies still don't seem to grok that selling their software in Europe (and Asia for that matter) is more than just localizing the on-screen text.
Anyway Loïc is going to rip the EU to shreds.
Here's his post on scalability of photo albums - my response below.......
Dealing with thousands of pictures in iphoto. My "switching" has been very well, now my 8 years son and my wife also have macs and they love them. The only issue we have is with our 6000 digital pictures. The mac gets really slow when iphoto loads them (even the 1.8GHZ G5 I just got woah). So the solution is probably to create different photo galleries (I do not know the iphoto word in english, the French is "phototheque") and save them on cds or dvds but it is not convenient as you do not have all your photos nearby. Apple will probably improve that soon. Any thoughts of you having the same problems with large photo galleries ? Thanks [Loïc Le Meur's WebLog]
Ah yes - welcome to the world of photo management, digital lifestyle aggregators and scalability.
Many have attempted to solve this challenge (as I often tell Paolo - nothing is a problem, just a challenge.) I'd say the best solution right now is to have a dedicated media server machine - on-line - all the time, connected to your Home LAN. This way they're always there, everyone can get to thema nd use them, but there's nothing to bog down your main machine.
There are lots of more detailed, technical solutions - including indexing all your photos with the dreaded M word (meta-data), and (one of my favoties) embedding hot zones into the photos (ala Greg Elin's Fotonotes) - but in general you really need formal photo management software.
Products like Canto's Cumulus were invented for just this purpose. Adobe has a much more lame product - called Album.
