Hi UC,

This may very well be an error in my installation, but I've installed image_gallery similar as in the past and when I try to import from existing FileStore images into an album, I get:

[Notice] Trying to get property of non-object
POST /admin/EditForm/field/GalleryItems/UploadifyForm?SecurityID=508831148&ctf[GalleryItems][start]=0&ctf[GalleryItems][per_page]=10&ctf[GalleryItems][showall]=0&ctf[GalleryItems][sort]=SortOrder&ctf[GalleryItems][sort_dir]=&ctf[GalleryItems][search]=&ctf[GalleryItems][filter]=AlbumID_1&ctf[GalleryItems][view]=grid&ctf[GalleryItems][imagesize]=100

Line 140 in .../image_gallery/code/ImageGalleryManager.php
Source

137 	public function getPreviewFieldFor($fileObject, $size = 150)
138 	{
139 		if($fileObject instanceof Image) {
140 			$URL = $fileObject->SetHeight($size)->URL;

Do I need to set a relationship in Page.php or Photo.php to fix this? Like, say:

public static $has_many = array (
	'Album' => 'Photos'
);

As always, thanks!
Wilson

I should add, that I can upload from my machine and also import into the gallery outside of albums.

I am also getting the same behavior.
I will add that I am also having a hard time uploading to a specific asset folder. It seems to always put new images in the root of the asset folder.

I am experiencing the same issue - Wilson, did you find a solution for this?

Last time I checked, I was still getting it. In the meantime, I plan to train my clients to upload rather than 'Choose Existing', when they ask.

UC explained in another similar thread, that's it quite a difficult issue due to a single image needing to be two classes. Someone else posted a 'many many' data model (I believe) that may be the answer. I'll try and find the thread. Or if you find it, let's put the link here.

I am extending the ImageGalleryPage and I think this is the problem...
