ahhh, ok, that would cause the problem right there.
when you add Power CMS Builder to your site it will try to create a folder in the root called images, Since you already had a folder named images, it put the image files in your image folder, but by using a capitol I for the folder name, it is causing the PCMS Scripts to fail, this will happen on linux based servers where the folder names are case sensitive.
you should rename the Images folder to images.
