Hi Ed,
No, not at this time. That is something that has been requested before, so I will put it on the feature request.
As I think about it, you could actually accomplish something very close to this now, but the upload form would have to be on a separate page, and everybody's images would get loaded to the same gallery (that would never actually be show to the public if you didn't want to), and then be displayed separately in a Contributor gallery. Ex. http://smashly.net/blog/author/byron/
There is a feature for turning on Contributor Galleries under PhotoSmash Settings / Special Galleries. This will add a gallery to the author's page in WordPress that will show all the images they have uploaded, and anyone can view.
So, to show the form without a gallery, you could do a shortcode like this:
[photosmash uploadform_visible=true no_gallery=true id=XX]
This would display the form without having to click the Add Photo link...it would just be visible. No gallery would be shown. "id=xx" is the id number of the gallery you want to upload to.
So everybody can upload there. Then when you want to see their images, provide a link to the Author's page.
That would be the trick, displaying the link to the author's page. I think there is a plugin for that, but maybe not. If you're a PHP coder, you could probably hack together something that would do it in 30 minutes or so.
At any rate, I'll put the features on the roadmap.
Cheers,
Byron
