For creating, go into the Scanner sprite, and paste an image on any kind into the Textures32 costume. For viewing, you MUST have a TXT file on hand. Right click the SCAN list when it appears. (PLEASE click see inside before right clicking!!!) Then, click "Import" then choose the TXT file you have. Finally, type anything into the bar, then press the checkmark.
