Hello, I'm looking for an extension to optimize my images already saved on my server (equivalent to "add from server on wordpress) thank you for your answers

There is no such extension. You could just move/copy the images via FTP to the "albums" folder instead since Zenphoot is file system based.

thank you, so no possibility of catching my error loading my 6000 photos in hd on my server :-( http://www.la-planete-coconiut.fr

Sorry, Zenphoto will generally not modify the original full images uploaded as it creates the required display sizes like thumbs from them. That is useful if you use a another theme that uses different sizes that then can be generated from those images.

Thanks again for this information
