I had an answer from Felix Turner, author of SimpleViewer.
I'm not gonna transcript our whole conversation, but here are two sentences:
As far as using SimpleViewer with Coppermine, I think this is a good idea.
However, because this project has the potential to be used by a large number
of users, I would prefer the SimpleViewer download link to remain visible.
This makes sense to me, and i understand his point of view, and plan to respect it.
Everything cannot be open source - free of use, Felix makes nice innovative products, want to get some recognition and $ for it, nothing more normal.
Moreover, i realized today that the thumbnail size which had to be used with this viewer had to be of a fixed sized ( 45x45 ) and couldn't be cutomized through the options of the xml in input, so that would make
another modification to make it fit in a nice way with coppermine.
What i'm looking for is to integrate this kind of flash viewer with cpg - imo it would be highly innovative for an open source php gallery - but i said the words, i'm looking for an open source one (flash included), therefore customizable by anybody, and which would
fit with coppermine since it would be
made&designed for.
I'm gonna head this way and I'm up to start from scratch (or not entirely,
www.amfphp.org looks really interresting and could make things a lot simpler..) and i think that on this one there's enough work for severals ( reflexion, design, conception - php & flash )
So if there are serious and motivated people...let me know your thoughts
