An was very busy. Anyway currently studying how to use smile for distributing presentations without the need of uploading images on SL.
The theory should be the following:
1\ build a server on my php server domain being able to serve smil output.
2\ functions handled might be the following:
3\ http://url/smil/text.php sending via post a text composed to up of 600 chars and define a font and dimension, will receive back a smil with a textual slide
4\ http://usr/smil/graphics.php sending via post url of an image, a title and a description and have it returned as a service with proper formatting.
This should avoid uploading images to SL.
