Can I change the images?
Yes, you can. You only need to edit the two images in the directory 'images' of this plugin. It also includes the .psd files for your convenience.
Does it works with IE?
Yes! IE 6 included!
If you speak Spanish, why the hell did you do this plugin in English?!
Wow, take it easy ;). The next version will be translatable and will include the translation into Spanish. So... relax :D
Any warning?
Well, yeah. If your theme's stylesheet modifies the body's width, PageCornr will look bad. Use a Wrapper and modify the width from it. In that way, PageCornr will stay in the corner.
