I want the next button to link to the first image of the album when the last image is showing. I don't see a function that give me the link to the first image.
any ideas ...?

There is no function/option for that. This should work:
`if (hasNextImage()) { <print normal link to next image>

} else {

$firstimage = $_zp_current_album->getImages(0);

echo "<ahreff='".getAlbumLinkURL().$firstimage.".php"'>Next</ae>

}`

(Codetypos on purpose because the "damm" forum makes a real link out otherwise...)

or you could possibly just add a function like getPrevImageURL() and call it getFirstImageURL() in template-functions.php, something like this I think:

`

/**

* Returns the url of the first image in current album.

*

* @return string

*/

function getFirstImageURL() {

if(!in_context(ZP_IMAGE)) return false;

global $_zp_current_album, $_zp_current_image;

$firstimg = $_zp_current_album->getImage(0);

return rewrite_path("/" . pathurlencode($firstimg->album->name) . "/" . urlencode($firstimg->filename) . im_suffix(),

"/index.php?album=" . urlencode($firstimg->album->name) . "&image=" . urlencode($firstimg->filename));

}`

@acrylian: echo `<ahreff='".getAlbumLinkURL().$firstimage.".php"'>Next</ae>` didnt work. i had to change $firstimage to $firstimage[0]. That did the trick thanks.

@gerben: thanks for looking in to it, i decided to use acrylian's method because i will forget that i changed the functions file and with an update i will get lost This way it is easy for me to change if necessary.

I actually just added this on my site, i just made that getFirstImageURL() function and similarly a getLastImageURL() function to get the url to the last image in the album.
to get the last image I used:

'$lastimg = $_zp_current_album->getImage($_zp_current_album->getNumImages() - 1);'

and then I changed the links to the next and previous picture in image.php like this:

'a href="<?php if (hasPrevImage()){echo getPrevImageURL();} else{echo getLastImageURL();}?>"'

'a href="<?php if (hasNextImage()){echo getNextImageURL();} else{echo getFirstImageURL();}?>"'

This works fine.

@MarcelSpijker: Ah, sorry, that typo was without purpose..:-)

@gerben: Good one, too.

Would these functions also work to add "first" and "last" image _in addtion_ to prev/next?

<<First>> <<Prev>> <<Next>> <<Last>>

Yes, they just return a link to the first and the last picture.

As a note we have included both functions in the next nightly build.
