Hack:   Giving a PowerPoint Presentation in Second Life
Subject:   Very Good...but consider this as well...

A large presentation consisting of many individual images becomes "costly" in uploading fees.


My solution to this problem is to upload your images to a webhost (preferably a free host account)and use the llParcelMediaCommandList()function to load the images onto the PrimFace, since BMP, GIF, TGA, and JPEG file formats are supported.


In effect, this becomes a frame-by-frame "movie" if you will, however with its own drawbacks, such as the 2.0 second delay for the function, the need for a more advanced script, as well as any other problems that may arise.


But, as an alternative to paying $L10 for each upload, it has served me well thus far.


I have SUCCESSFULLY used this method in teaching my Basic Scripting classes in the past, and due to the fact that my "script-images" change so frequently, it has become a more economical, albeit less-efficient, method.

    I think that in order to actually invoke llParcelMediaCommandList(), you need to acquire land in SL; isn't this so?

    In order to use your proposed solution, I would have to fork over $USD72,00 to become eligible to own land, and then actually buy land (at $USD10,00 -- I think -- don't quote me on the latter number).
    It would seem that you could upload a lot of jpegs for $L10 per image before reaching a crossover point.

    Perhaps I am wrong about needing to own land before being able to invoked llParcelMediaCommandList()?

    I may be wrong about this, but here's what the official documentation (see http://lslwiki.com/lslwiki/wakka.php?wakka=llParcelMediaCommandList ) has to say:


    
You are allowed one movie (or "media" resource) per land parcel. The movie will be played by replacing a texture on an object with the movie. Users will only see the movie when they are standing on your land parcel. Otherwise they will see the static texture. Script functions only work for objects owned by the land owner or deeded to the group that owns the land. (Remember to set asset permissions on your script and object as well as sharing it with the group!)

      $USD72? The premium account costs $US10 a month, and you can then buy a basic 512 sq m. plot with no extra cost.

      Of course that's pretty cramped for a presentation. But if you're a professional educator, why not press your institution to pay for their presence in SL? Classrooms in RL cost an awful lot more.
      • I love the presentation script!
