PhpWebGallery versions 1.5, 1.6 and 1.7 all require PHP, Mysql, a web server (Apache for example) See PhpWebGallery requirements
The installation process is handled by install.php. Follow instructions and all should go smoothly. Screenshots are taken from release 1.6. Same apply for 1.7
First of all, download last version (clicking “last version” in the header of this page may help...)
Then uncompress the file (phpwebgallery-1.6.0.zip is suitable for windows) in a folder you choose, (desktop chosen in the screenshot). This will lead the contents of the archive to be in a folder named phpwebgallery-1.6.0 on the desktop.
Upload the whole directory on your webspace with an FTP client; FileZilla used here.
I strongly advise to rename folder from phpwebgallery-1.6 to phpwebgallery for example. The main goal is not having the release version in the name, because it may change in the future ( upgrade )
Using your browser, go to the installation page, something like :
