Salut, il n y pas que ca comme dossier de Chmoder je te fais une copier coller du Faq de coppermine :
What are the steps to get Coppermine running?
as stated in the Coppermine readme file:
1. Download Coppermine
2. Unzip it to your harddrive
3. Upload the contents of the coppermine folder to your server (you can install it in the root or in a unique folder with a name of your choosing).
4. CHMOD (CHange permission settings MODe) your newly uploaded Coppermine "include" and "albums" folders and subfolders to allow for read/write access. If your webhost does not provide file management tools to let you do this, you will probably need to search the net, download and install an FTP program to facilitate this.
5. Create a database with your website management tools if you don't already have one. You do not have to add any tables to your newly created database. Coppermine will create them for you. If you already have a database on your site, Coppermine can use that as well.
6. If you are installing on a Yahoo Webserver, read this thread first.
7. Point your browser to
http://www.yoursite.com/coppermine/install.php and follow the directions of the install file (basically the mySQL-tables will be created there and the config table will be filled with default values)
8. Upon successfull installation, delete the install.php file from your website.
9. Point your browser to
http://www.yoursite.com/coppermine/ , and login as admin using the ID and Password you provided during install. In admin mode, click on the CONFIG menu button to start customizing your coppermine photo gallery.
10. Experiment with your new install, create a few categories, sub-categories, and albums. Upload a few pics (not too many, just yet), test if everything works.
11. Point your browser to
http://www.yoursite.com/coppermine/docs/ and READ the docs. The documents included with CPG1.4.x have been updated from previous versions to help answer your questions and issues so that you can get the site you want the first time out. Reading the docs takes but a few minutes. Resolving issues after the fact can take days, even weeks.
12. If your new Coppermine install is in a sub folder on your site, publish your site by linking it to your homepage.
