If your images are being served elsewhere, then you won't be able to use the Image Folder Widget. At this time, there are no alternative content options for you. You may be able to set up a slideshow on a website, then use the Web Page Widget to display that slideshow, but you're talking about a lot of work there.
Rise Storage really does make things easy, especially for the price!
Our 'slideshow managers' use the Photo Album widget to control the varied content of their own campuses' slideshow images by using Picasa to tie into their Google accounts.
That tie-in lets these 'slideshow managers' from different campuses choose the images that play on the slideshows on their own campus by managing that tied-in "public on the web" Picasa folder. They're able to manage their campuses' slideshow's content without our involvement. They love this automation and control.
Is there going to be an option to replicate this self-management of image slideshow content after the Photo Album widget is gone? Or will RV storage now be the only repository that works with whatever the next Photo Album will be named?
