steganography, Uploading on the Cheap, and Moving Notes in Bulk


Needest thou to save a Linden for your uploads or perhaps transfer a goose-load of notecards from one grid to the other? Here's how!

Steganography (US i/ˌstɛ.ɡʌnˈɔː.ɡrʌ.fi/, UK /ˌstɛɡ.ənˈɒɡ.rə.fi/) is the practice of concealing a file, message, image, or video within another file, message, image, or video. The word steganography combines the Greek words steganos (στεγανός), meaning "covered, concealed, or protected", and graphein (γράφειν) meaning "writing". - Infogalactic

This is something neat that many builders and meshers are aware of but many regular users may not know about. For those of us who live on multiple grids (SL and the sundry OpenSim clones of SL that exist), here are two tricks for uploading images to SL on the cheap and for mass importing notecards so you don't have to do all of that copy-create new notecard-paste from one grid to the next. 

Re textures: So let me also mention that your departure grid needs to be an OpenSim grid since you will need to first upload the texture to that grid. The reason you do this is that most OpenSim grids do not charge an upload fee. 

The first one assumes you needed to upload an object or linked set (otherwise, the economy of this is lost).

  1. On the departure grid (where you will create or find the FP object you want to use to encase your lovely texture), place the pic inside the object. 
  2. Save it to your computer. 
  3. Upload that .oxp file to the destination grid. Bingo: you have both the object and the picture for one low price of 10L (instead of 20L). Note: There seems to be a hard limit of one texture per object - when I added more textures, they were stripped out during the original upload). Also, to ye pirates, the permission system will strip out anything that isn't full perm (please respect IP). 

The next trick is basically performed the same way, except that this time you dump your notecards into the object and retrieve them at the other end. There doesn't seem to be a limit on the number of notecards; however, it does seem to do some weird things to how they're named if you give them numbers (as seen in this pic, it renamed some of them after they were uploaded). 

 

So there you have it - two new tricks to show your family this Thanksgiving. laughing
