This screenshot shows PHPture with the projects-panel on the left collapsed. The image in the viewer is zoomed to it's orgiginal size, and the keyword-window is floating over it.
Here the projects-panel is visible again, floating over it is a window containing the master image.
Instead of thumbnails the browser-panel contains a table with information about the pictures. The darker rows are stacks of grouped pictures. The image in the viewer is automatically scaled to fit.
