Size of the stage must be size of your photos to display them on the full stage. The script calculates the radius of the carousel in function of the stage size. However you just need write values that you want for X and Y radius (constants : CARR_RAYON_X and CARR_RAYON_Y) to change dimensions of the carrousel. For a faster loading, this carrousel loads 80x60 thumbnails (in the "diapo" subfolder). You can use thumbnails with others dimensions by changing DIAPO_LG and DIAPO_HT constants. TIPS: To generate many thumbnails automatically from a folder use Photoshop (images processor) or a free software like XnView.
