The major difference between this post and the previous is that the new version uses Actionscript 3. Here is the deep linking example of SimpleViewer 2 and SWFAddress 2.4.

What you will need to download:


Make a new folder on your desktop – you can call it whatever you would like, for the tutorial I’m going to call mine gallery.

Extract the file you download from the SimpleViwer site, simpleviewer-pro.zip.

Copy all of the files in the flash_embed folder into your gallery folder. You will find the Flash Embed example in the SimpleViewer folder you created when you extracted the simpleviewer-pro.zip under simpleviewer-pro2_1/examples/flash_embed.

Rename simpleviewer_flash_embed.fla to simpleviewer_swfaddress.fla, delete simpleviewer_flash_embed.swf and simpleviewer_flash_embed.html.

Unzip swfaddress-2.4zip

Copy the asual folder found in swfaddress-2.4\dist\as\3\com\ to gallery\com\.

Copy swfaddress.js from swfaddress-2.4\dist\js to the gallery folder.

In the gallery folder right click new>text document. Rename the text file to index.html.

You should now have all of the files you need in the gallery folder:

  • com folder
  • images folder
  • thumbs folder
  • gallery_1.xml
  • gallery_2.xml
  • index.html
  • simpleviewer_swfaddress.fla
  • simpleviewer.swf
  • swfaddress.js

In your gallery folder open index.html and copy the following code into index.html:

In your gallery folder open simpleviewer_swfaddress.fla with Adobe Flash Professional. Delete all the buttons and the text box, with the exception of the Load Gallery 1 and 2 buttons. (Feel free to change the background color so it’s not so hard to look at.)

Save (Crtl + S) simpleviewer_swfaddress.fla.

Export (Crtl + Alt + Shift + S) simpleviewer_swfaddress.fla as simpleviewer_swfaddress.swf into your gallery folder.

To test you must upload the files to your server.

Make sure to upload all of the following files and folders:

  • images folder
  • thumbs folder
  • gallery_1.xml
  • gallery_2.xml
  • index.html
  • simpleviewer_swfaddress.swf
  • simpleviewer.swf
  • swfaddress.js

The browser history is updated every time you click a thumbnail, thus enabling the browser back button. You can now link to any image via a nice URL and as you click on thumbnails you can watch the address bar change. You can also directly link to an image.
