ID Conflict with non-media manager images

How to you keep from the plugin automatically adding the Page ID to rel=”prettyPhoto”?

I have several images on a page with the rel=”prettyPhoto” tag which are independent of each other. Yet, when clicked, the enlarged image will allow you to view every photo on the page in the slide show — I do not wish this to be.

I have attempted to add [gallery-1], [gallery-2]… and so on to each individual photo, but prettyPhoto removes those efforts and replaces it with the page ID instead.

Please note that these images are being linked to files in a folder on the drive, not to images uploaded via the Media Importer. — I have done it this way b/c there is no good solution for managing photo groups (as in folders) in the WP Media Manager.

Any thoughts?

Thanks
