To download the zip file containing the tube, just click on the thumbnail - you will then need to use a zip file extractor such as winzip to extract the file to your harddrive or disc. If you left click the thumbnail, the file will download to a temp file, and winzip (if you have it) will automatically open; if you wish to save the file somewhere on your computer to unzip later, right click, and choose "save target as". All files are in .psd format, and should be compatible with any version of PSP, as well as PhotoShop. They can be used as is, or opened in PSP and installed in your tubes folder (File/Export/Picture Tube). While PhotoShop does not have a "tube" tool, they can be opened in PS to copy and paste.

Note: Percentage on the thumbnail is the relationship in size to the actual tube - for example, 75% means the image shown is the actual tube at 75% size.
