We need a photobook on DVD that you can browse just as windows explorer, the images should be displayed full-screen (like when you use infranview) and display a price (the price is part of the image name). Pressing escape takes you back to the windows map-structure. Upon loading the DVD into the PC a menu should apear saying: 1. Browse our catalog 2. Check for updates 3. view updates When the user chooses option 2 the an application on the disc should check/create a temp folder on the PC. The next step would be that new images should be uploaded to the temp folder. Now, the index file from the content on the DVD should be merged with the index file from the update. The purpose of the DVD: We have a huge catalog of DVDs, we have them categorised in maps: label / Sub-label. We want our customers to have this on disc, but we also want to offer them updates over the web. We prefer to have a solution that is ready to use without installing anything.
