To re-order your photos using the Metrixstream Content Management System (CMS) photo manager feature:

Log into your Metrixstream CMS account

Navigate to the top menu option "Browse"

A drop down menu will appear. Select the "Content" menu option in the drop down menu.

This will lead you to a page with a list of all content you have uploaded to Metrix.

Find the photoset you want to reorder by entering that photoset's name or you can do a search by selecting "photoset" under the "type" drop-down menu option. This will filter the content to only show items that are photosets. Or you can simply go through your content by page if you aren't sure of the filename.

Once you have located your photoset, click the thumbnail and that will take you to the properties page for that photoset.

Under the list of thumbnails, you will see two buttons with the options "Edit properties" and "manage photos". Click the "manage photos" option.

This will place you on a page with a list of photos that are in that photoset. 

To the far right of each photo, there is an "X" that allows you to delete that particular photo.

Click the "X" of the corresponding photo/ photos. 

When you are done, scroll down to the bottom of the page and click "Save".

This will place you back onto the "Photo Properties" page.
