I d/l the latest version last nite, and got it working, but I had to FTp my mp3 files to the /files/ directory.
Once the files were there, I hit the flag for 'external file', typed the full URL of the filename, and hit upload..and it appeared on the file list. Another problem is that the graphics in the /theme/ directory are not linked to properly. I had to edit the PLUGIN to remove some extra '/' and then, move the button graphics from the /theme/ directory to the directory that the /theme/ directory is in. After doing that, the graphics appeared.
Upon putting the linking php code on the page, and playing with that a little bit (look at the README file in the download) I was able to get those on the page.
Take a look.
The controls are on the right side mid page.
I did notice that the player does NOT work in Firefox, tried on 4 different Firefox computers today.
What's up with that?
Did download a demo of Wimpy Player to look at. Also, consider Radio.Blog, now at version 2.3. I've seen one blog running this, and have played with it on other sites. Looks like a good opportunity.
