I would have gladly rated it "excellent", but for the fact that the module vsir does not work on a live site. I am using Joomla 1.7. While the module works like a charm on localhost, it merely shows "No images" on the live site. I have ensured that the images path is correct (it is the same as on localhost); and "caching" is set to "no" on both localhost as well as live site. Further, the "cache time" is set to 100 in both the places. Since the module works so well on localhost, I would love to see it working on the live site too. Unfortunately, I did not see any 'Contact developer' link on their site in order to communicate this feedback to them.
This issue should be solved in the current package where we make sure the required mootools files are loaded.
