UPDATE: Resetting the plugin to default settings fixes this issue. As far as I can tell, the only settings I am able to change without breaking the plugin’s ability to create thumbnails when uploading new images to a gallery, is thumbnail size, and changing the gallery settings to display the gallery thumbnail, rather than a link to the slideshow. LITERALLY ANYTHING else I’ve tried to change in the settings results in the same old, “Create Image Failed” error when creating the thumbs at image upload.
I wanted to follow up on this thread to make you all aware of this issue, so that you may be able to fix/patch it.
Thanks,
Troy Cono
