Try asking in Lazarus forum (http://lazarus.freepascal.org/index.php?action=forum).
I'm using it only for Imaging demos - very rarely.

I got the same issue. Any help would be much appreciated.

PS: I did have it all working in Delphi

Hi, when I add images using ImageList Editor they do not show on my TreeView, in Lasarus.
Also, Going back into the editor, only the first image remains, even after using save all. 
Do I need to notify Lazarus of the file name I chose?
Many thanks
