Some functions (getHeight(), getFullIlage()...) give me a php error.
It seems the problems is with all functions from file class-image.php,

Any idea ?

When do you get that error? Meaning what do you do when this appears? Do you use a standard theme?

I'm using a personnal theme based from Cimi and Default.

I just just put a echo getFullImage(); (for testing) in my template because I need the real path of the picture.
Doing the same with Default theme -> same error

Try with get FileName(), getAlbumName... -> same error

Seems you have a typo in your theme's image.php, there is no function getFullImage()but getFullImageURL().

Both seems exist

http://www.zenphoto.org/documentation/elementindex.html#g

getFullImage
in file class-image.php, method Image::getFullImage()
Returns a path to the original image in the original folder.
getFullImageURL
in file template-functions.php, function getFullImageURL()
Returns the url to original image.

True, but getFullImage() is a class object method that you can't use directly, it needs to be use like $_zp_current_image->getFullImage() for example, otherwise you get an error. getFullImageURL() is the template equivalent.

Thanks acrylian!
But it's too difficult for me.

What exactly is too difficult? Looking in the source code and replacing getFullImage()with the correct getFullImageURL() should be doable I think.
