Hi,

I'm using SS 2.3.7 and modules-image_gallery-r390.

The upload and display of images works perfectly, but when i view the "files and Images" tab in the admin section, and then go back to the gallery, the thumbnails icons of the images have turned into a blank file icons (in the photo tab) and when i view the published site the images are missing. When i click on the blank file icon in the gallery under the photo tab i get the following error:

[Notice] Trying to get property of non-object
GET /admin/EditForm/field/GalleryItems/item/15/edit?ctf[GalleryItems][start]=0&ctf[GalleryItems][per_page]=10&ctf[GalleryItems][showall]=0&ctf[GalleryItems][sort]=SortOrder&ctf[GalleryItems][sort_dir]=DESC&ctf[GalleryItems][search]=&ctf[GalleryItems][filter]=AlbumID_3&ctf[GalleryItems][view]=grid&ctf[GalleryItems][imagesize]=100

Anyone else experienced this? I tried downloading the newest version of image gallery and using the imageGalleryManager.php which did not help, so put the old version back in.

Cheers,
Rob

Looks like I've just had a similar issue.

Added a file and then used "look for new files" and it added the additional file I had uploaded, however all image galleries on the site are now no longer working, just showing the missing image icon on the preview.

Using SS 2.4

Ok it looks like the problem for me is happening when "Look for new Files" in Files and Assets is clicked.

Process being followed is

Images are bulk uploaded via FTP into the Assets dir, these images are then added to a gallery which works fine. However the next time the "Look for new Files" button is clicked it seems to remove data from the database that links the galleries to the images (assumption)

The correct number of images are showing in the gallery, but all as missing images. It could be that we need to do this an alternative way, but I'd be interested in knowing

Keep me posted, guys. I can't replicate this one, but when you find a causal link, let me know and I'll start digging in.
