Topic: xml file / filling with pictures

i am interested in buying the simpleviewer pro.
some questions:
- can the tool be customized so that one does not need to "write" all picture file names in the xml file, in other words so that the viewer automatically shows all  uploaded pictures (without touching the xml)?
In combination with using the pictures themselves as thumbnails that would save a lot of time when filling with (lots) of pictures (captions are not really necessary).
- I further do not need flash, to 'unbrand' the viewer?
thanks for your help,
