Pic Tric


 
JohnDodson Have you ever noticed in Activ 4.22 that your html files are now encrypted when they are extracted into the temp folder?  The pictures however, are still pictures and can be easily copied.

If you would like a little protection from the average user here is what you can do.

Step 1)  Turn on the extensions on your computer so that you can see the .gif or .jpeg and so on when you open the "source" folder that your pics are in.

Step 2)  Rename the pics so the average person will not recognized that it is a picture.  For instance mypicture.jpg, rename it to zfile1.xds or whatever you want.  When you do this you are going to be prompted by windows that if you change the extension it may mess it up.  "Are you sure?"  Click Yes.  Now your picture looks like a windows file with some crazy extension.

Step 3)  Put the image tag exactly where you want the picture displayed. <img src="zfile1.xds">.  It will look like this example if the picture is in the same folder as the html page.

Step 4)  Compile your ebook and check it out.  Iexplorer will display the picture.

If you want to make a hyperlink to the picture do this:
<a href="zfile1.xds">Large Picture</a>

If you want to make a thumbnail link to the picture:
<a href="zfile1.xds"><img border="0" src="help.bmp"></a>
The src="help.bmp" is the thumbnail that is displayed to click on and the a href="zfile1.xds" is the full size picture.

If you want to make a thumbnail that goes to a page that has the full size picture inserted in it:
First make the page and insert the picture as in Steps 1-3 and then save the page, the picture, and the thumbnail in the source folder.  Then put this code where you want the link:
<a href="pagename.html"><img border="0" src="help.bmp">
Again help.bmp is the thumbnail.  Which you can also do the thumbnails the same way to disguise them. (Rename them as in the steps)

Now having said all that, if you use an editor such as Frontpage, when you try to insert the picture into a page the editor will tell you it can't because it does not recognize the format.  So you will have to put this coding in by hand.

The result is:
If a person copies the picture out of the temp folder and saves it to their computer, when they double click on the picture it will not open.

Now this will prevent about 50% of the picture theives out there because 1 they don't recognize the name of the picture and probably won't save it to their computer, 2 if they do save it and try to open it, it won't open automatically and they will have to tell windows what to open it with.

Will this stop a rocket scientist?  No, but it is some protection against the average person.

Hope you like the idea.
Love to hear from you.

John
