I got to know about TiltViewer from Visual-Blast. Thanks to the author for the useful information.
TiltViewer is a free flash application by Airtight Interactive for online picture gallery. At first, I thought I need to reupload my gallery to my web hosting account in order for TiltViewer to work, but I found out that it’s using an XML file so that picture URLs can be inserted there. Well in that case I can generate the XML file using PHP script which will take PicasaWeb RSS as an input.
So what do you need in order to be able to show-off your album PicasaWeb albums gallery using TiltViewer?
