2005 Corel Paint Shop Pro Photo releases: 2006–2008 Corel PaintShop Photo Pro releases: 2010-2011 Corel PaintShop Pro releases: 2011–present Picture tubes Picture tubes are graphic images with no background. They are often used as a starting point for complex images; that is, they are combined with other image elements to produce a final work. Tubes can also be regarded as graphic brushes based on a pre-created image; this was their original use. Instead of leaving a trace of color on the canvas, they would leave a trail of images. Popular tube subjects include alphabets, humans (also known as dollz), animal and toy figures, flowers, love messages and seasonal symbols. The tube system originated with PSP Pro version 5. Native tube files may be in .tub, .psp, .pspimage, and .psptube formats. XnView, IrfanView, and TubeEx are separate graphics programs that can convert tube files (.tub) to .png. Ultimate edition PaintShop Pro Photo X2 Ultimate was released towards the end of life of PaintShop Pro Photo X2, in September 2008. It included 150 additional picture frames and Picture Tubes, the programs Background Remover, Corel Painter Photo Essentials 4, and Photorecovery, as well as RAW support for 250 cameras and a 2GB flash drive. Subsequent Ultimate editions were released contemporaneously with the basic version. PaintShop Pro X4 Ultimate included Nik Color Efex Pro 3.0, a voucher for 21 images from Fotolia at high quality, and additional Picture Tubes. X5 Ultimate included Reallusion FaceFilter Studio 2.0, NIK Color Efex Pro 3.0, and "over 100 unique brushes, textures and royalty-free backgrounds". PaintShop Pro X6 Ultimate includes Athentech Imaging's Perfectly Clear and Reallusion's FaceFilter3 Standard. PaintShop Pro X7 Ultimate includes those same two items. The bundled extras cannot be installed unless that version of the PaintShop program is already installed. However, once a bundled extra such as a plugin has been installed, the installed files can be copied to other versions, e.g., a plugin installed under X5 can be copied to X6 and even if X5 is then uninstalled, the plugin will continue to work under X6. Corel releases a new X version roughly annually, so this ability to copy means PSP users do not have to choose between updating or continued use of Ultimate add-ons from previous versions.
