Graphic Files in Second Life and creating Powerpoint slides

Graphics file formats supported in SL:

TGA, JPG and BMP, and now PNG. The ones that support transparency are TGA and PNG for creating items like clothing and objects such as windows.

Second Life pictures that you shoot from Second Life are BMP files and should be converted to other file formats because they use up so much memory.

Many people use Photoshop to create TGA and PNG files, but some thrifty educators use the free GIMPshop and Paint.NET (which just added support for saving 24-bit PNGs).

If you are in a hurry and it doesn’t matter if you have transparency or not, here is a simple solution to obtain JPG images for SL uses:
Create a Powerpoint presentation. Then when you save it, click “save as JPG.” This saves all the slides in the presentation as individual JPG images in a single folder. Then, from SL, you click Upload, then “bulk.” You browse your computer’s folders, find your folder and then hold down the Ctrl key to choose your files. Or, you can choose the first slide, then scroll to the last slide and press the Shift key to highlight all of them.
Many educators use this method, since they still have the original Powerpoint presentation to use in RL, while they have the same slides in SL. This enables them to use the same material between RL and SL. There is a charge of 10 Lindens per slide. This quick method is useful for creating signs to use in SL also, but ensure that the text is larger than 24 points so that they are easy to read.
When hosting an event in SL using slides, the area supporting the event will usually give instructions to the presenters a week prior to the event. The presenters usually give them a SLURL to the area and a “practice” area with a slideshow viewer so they can practice uploading their slides and using their presentation. They also designate a small area where they are allowed to place their posters and graphics.
