[development] Custom Directories

Greetings, I've run into a "best practices" question, I've created a directory (i) inside the sites->default->files->i for storing thumbnails and custom logo and manually placed the thumbnails there. Linking to the thumbnails with a text link. Upon a:hover, the path to the files directory( sites/default/files/i) appears in the status bar. Is this customary or have I forgotten a setting in one of the path modules, that would obscure this? CK
