OscMax V2.0 RC3 How to adding multiple images via Admin Panel??

[triconstore]

HI guys
im new to Oscmax
mine is OscMax V2.0 RC3 and tried to follow instruction below to upload images via Admin panel. but it fails. could anyone advise?

below is from link http://wiki.oscdox.com/dynamic_mopics

Hidden Feature for additional images
For uploading images via Admin. (not required in 2.5 RC2 onwards)

Once you have become familiar with using the automatic thumbnail system, the following can be tried. This assumes that you have not changed the default Dynamic MoPics Image Pattern.

Example:
You want to upload two Product images (for the same product) called product.jpg and product_1.jpg

Add/Edit the new Product and upload product_1.jpg first
Click update so that you can see the preview page (you will notice the green message bar saying that the image has been uploaded.)
Click back and this time click the choose image button and select (the main) product.jpg image.
This sounds more difficult to read, than it is in practise - Try it! Just remember to upload the main image LAST.

Let me guess, you installed it from your hosting provider's automatic system?
osCMax RC3 : Aug 4 2006

The wiki, in that section refers to software of only a few years ago. onwards.
osCmax 2.0.15 : Feb 9 2010

The above is possibly the first time that image management got to that level.
