EDUCEDGE,

Several techniques exist:

1-$10 per upload via the SL UI: simple click, browse, upload. Your pic (.jpg) shows up in your texture folder

2- Flickr2SL board and Flickr stream: Miki Gymnast’s Flickr2SL is free (Rezzable 04 (152,111,648) but you must own the land for this to work.
How-to: upload images to Flickr, tell Flickr2SL board to look at the right stream, navigate the Flickr stram using a couple of button on the board. (Meredith Wesolowski, SLED 3/09/08)

Also Snagit has a plugin to upload any snapshots to Flickr. Other suggestions: pre-loading .jpgs of PPT -upload with Snagit and display with Flickr2SL board.

3- FreeView (Ross Perkins, SLED 3/07/08)
