Greg, Randy, Tom, Richard - thanks for kind words and feedback
Panfisher, that's a great question and the reason I posted this idea for discussion before moving forward with it. You are correct in that a photogallery will cost more money for us in terms of space and the use of a CDN (Content Distribution Network) to ensure the images are served up FAST. IMHO I think the biggest risk here still comes back to that idea of SIMPLICITY. If we put out a gallery that is hard to use or confusing then we are just wasting everyone's time along with money and resources that could be better spent elsewhere.
HCI and other usability factors are ultimately what makes or breaks "great new features" as I am sure everyone on this board has seen over the years. Keeping it simple is the hard part, change in itself is the risk. You can mitigate the risk of change by keeping it simple and intuitive to the end user. Money/Space - Yes (but of no worry to you), un-reversability - No, we can always switch the gallery feature off and use current way of simply posting to images forum.
One of the nice things about the photogallery is that if you upload an image to it, then you can use that image any other time you want to post it in the forum easily and without having to re-upload the same image again. Another cool feature is the ability to add "notes" to posts to explain exactly what the photo is displaying - in other words you could draw a box around someone's face and label it with their name, or draw box around spoon and label the name of the spoon, or maybe point out certain parts of an engine, etc. It's easy to get caught up with all the "cool" features of new software, but my main focus still remains on keeping it simple
Cheers
