Verification
Step 11. To verify that the picture pieces can
be re-arranged, a user needs to place directories (with picture
pieces) within their "Import Base
Directory" OR "Import Base
Directory" made to point towards the parent directory. In above example
"Import Base Directory" may be F:\winter . Any files placed in
OnInternet directory by PE Tool, must be placed at the internet
address/es specified at the time of encrypted picture pieces being saved.
Step 12. Using context menu in the Shelf, import .ks file created by PE
Tool. An Item will appear in the Shelf named "Encrypted Picture". Open this item
in Study Place, select the image and use "Encrypted Picture" from context menu
to initiate the process viewing encrypted picture.
A dialog box named "Unscramble" will appear asking for keyword, copy and
paste keyword from text file created for this image by EP Tool. Press
OK and picture should be seen complete, NJB
will collect the pieces from specified locations and arrange them
according to the keyword specified in "Unscramble" dialog box.
Distribution
To show encrypted picture to someone, a user needs to give them
.ks file, local directory (if any) with any
images included in it and above all the keyword to unscramble.
Make sure to place picture pieces on the internet addresses from
OnInternet directory if there is one.
What else ?

pieces, press Save button. All thiry six pieces will be placed
in either named directories for each piece or if they are to be placed on the
internet then OnInternet directory.
