are there any Sliding Panel Widget advanced commands?

I am working on a sliding panel widget and know all the basics triggers, such as next frame, last frame, previous frame, etc. however the webpage I am working on is going to allow for users to upload their images onto a pre-structured sliding panel widget, the image will then be placed on a specific frame based on the filename, for example when the upload "image 1" it will be placed on frame one, image two "frame 2" etc., the problem I would like to avoid is if there is no image that has been uploaded to a requested frame via the trigger is there a way for it to automatically be skipped and instead go to the next frame which contains an image?

Here are the basics which I am using.... sliding_panels.html

OK I found a trick that works after all. Since I am having members upload images to a database I am creating an new column with auto increment properties which generate the current number of the image they are uploading and naming it 'LATEST', create a recordset to display in DESCENDING order & filtering by a unique USERNAME also in the database -then add the PHP code within the sliding page script and it works perfect, takes me to the latest page the user has uploaded.


<a href="#" onclick="sp1.showPanel(<?php echo $row_Recordset4['LATEST']; ?>);">LATEST</a>
