I am trying to install this mod on my 1.5.5e store (the test version for now). I edited all the file names, uploaded all the files as instructed. I see the Image Handler3 under the Tools, and under the Configuration > Images, I also see all the new additional settings. Yet, if I go to Tools > Image Handler3, it says "No Image Handler information found." and when I click on Admin as instructed, nothing happens.

Now, I am wondering if it did install correctly or not. Since that mod works mostly "silently", how do I check?
