Hi guys,
I agree that it would be beneficial to:
1) See more photographs of printed models, and
2) use flags to be able to quickly determine which models have been printed successfully.
A fairly quick and simple (perhaps temporary) solution for (2) would be to have the community agree on a 'keyword' to use in the tags section of their models to say "this model has a 'successfully printed' photograph attached". That would allow users to search the gallery by keyword to browse only those models that have been successfully printed.
Here are a couple ideas that could help with (1):
(Now, I'm not saying this is necessarily a *good* idea, just a possibility).
Shapeways could offer a service to model owners for which the Shapeways staff would take a photo (or photos) of a model before it got shipped out to the person who purchased it. (Again, just a possibility.)
Another idea would be to add a check box, available to model owners, that would "allow buyers to upload photos of this model".
