where are the custom thumbnails

Hello all, thanks for the new feature 'Custom Thumbnail' , it's cool.
But could you tell me where are stored the actual uploaded files ? Or even better, how can I call the file for a given album on a page (not the thumbnail but the original file) ?
Thanks.

For each album (as well as nested album), I am going to upload a picture file for the custom thumbnail.
For the uploaded files, I'm thinking of using the following naming convention : albumName_header.jpg

On each album's homepage (i.e. albumBody.tpl), I want to display the corresponding uploaded picture (not the thumbnail) as a banner.
(here's an example in G1 : http://server101.totalchoicehosting.com/~severyn/gallery/aero)

I could use code like this :

<img src="{g->url href="www.myserver.com/g2data/plugins_data/modules/thumbnail/`$nameOfTheAlbum`/_header.jpg"}"/>

For such line of code, what's the correct variable name :$nameOfTheAlbum ?

Or, maybe, there's already a variable which points to the corresponding file, which would spare me from truncating the name with '_header.jpg'.

In this case, the code would look like :

<img src="{g->url href=$pathToCustomPicture}"/>

I hope all this makes sense...

Thank you Mindless (you're on every thread !).
I get a parse error (unexpected T_STRING) on layout.inc
I am way too ignorant to see if there's a typo in your code, or if it's something else...

It is embarrassing, but no, I don't really understand how layout.inc works, nor do I understand your code (again, I know html & css, that's it).

here are parts of my layout.inc file, so you'll see where I put your code.
The parse error is :
Parse error: parse error, unexpected T_STRING in /home/severyn/public_html/gallery2/layouts/darkglass/layout.inc on line 173

I still have the same error. I think I followed your directions correctly :

   /**
     * @see GalleryLayout::loadTemplate

    function loadTemplate(&$template, $item) {
    GalleryCoreApi::relativeRequireOnce('modules/thumbnail/classes/ThumbnailHelper.class');

	    list ($ret, $params) = $this->fetchParameters($item->getId());
	    if ($ret->isError()) { return array($ret->wrap(__FILE__, __LINE__), null); }
	    list ($ret, $bodyFile) = $this->_loadAlbumTemplate($template, $item, $params);
		list ($ret, $thumbnailImage) = ThumbnailHelper::fetchThumbnail($item->getId()); 
        if ($ret->isError()) { return array($ret->wrap(__FILE__, __LINE__), null); } 
	} else {
	    list ($ret, $params) = $this->fetchParameters($item->getParentId());
	    if ($ret->isError()) { return array($ret->wrap(__FILE__, __LINE__), null); }
	    list ($ret, $bodyFile) = $this->_loadSingleTemplate($template, $item, $params);
		list ($ret, $thumbnailImage) = ThumbnailHelper::fetchThumbnail($item->getParentId());
	    if ($ret->isError()) { return array($ret->wrap(__FILE__, __LINE__), null); } 
	}
	if ($ret->isError()) {
	    return array($ret->wrap(__FILE__, __LINE__), null);
	}
    $layout =& $template->getVariableByReference('layout');
	 if (isset($thumbnailImage)) { 
     $layout['headerImage'] = $thumbnailImage->getMemberData(); 
     }
	
	/* Prepare image frames, if available */
	list ($ret, $imageframe) = GalleryCoreApi::newFactoryInstance('ImageFrameInterface_1_1');

OK, no more error message, but the img doesn't come up. I get the following html code :

<img src="http://www.myserver[edited].com/g2data/plugins_data/modules/thumbnail//_header.jpg?g2_GALLERYSID=b0a7329b0b5934ec30df49bfd91e0b8d"/>

it's getting better, but still no picture : the img block shows, as well as the alt text, but not the jpg.

the html source is :
<img src="http://www.myserver.com[edited]/gallery2/main.php?g2_view=core:DownloadItem&amp;g2_itemId=201&amp;g2_serialNumber=1&amp;g2_GALLERYSID=d5ab8a6c8941814d17fcac5bb3e353bf" width="750" height="236" alt="chambord_header.jpg"/>

thank you for being so patient.

We're done ! It works !

Thanks again for all your help and patience. Now I'll try to finish my custom layout and post it as soon as it's ready.

Didn't even have to remove and recreate the existing custom thumbs.

Take care.

:cry:
[EDIT]
Scratch that...
I just went back on the pages and the images are no longer there. I tried to remove and recreate custom thumbs but I get a Fata error :

you appear to have a mix of old and new files on your site.. use the manifest check in upgrader step 2 to make sure you have a valid codebase.

if you remove the $item->getParentId() > 0 check from function isAppropriate in modules/thumbnail/CustomThumbnailOption.inc then the form will appear even for the root album.. (normally we hide it since you can't see a thumbnail for the root album anywhere...)

yup, that's the right way to upgrade..

fly.cub, showing an image in the album description is a good idea, looks great, eg. http://www.severyns.com/gallery2/main.php?g2_view=core:ShowItem&g2_itemId=395

did you just add html img code to the description field?

credit for the idea should go to http://www.frommel.net/gallery : it's a G1 design.
The author never shared his G1 templates so I started from scratch in G2.

there is a mention of the permissions thing above... http://gallery.menalto.com/node/29086#comment-104201
