We’ve just made MoreGallery 1.8.3 available which has 2 fixes for galleries that use remote media sources, such as Amazon S3.
First, the image width and height is now properly extracted and stored with the image record. Previously these fields would stay at 0.
Secondly, due to a check if the manager thumbnail was created that tried to re-create the image with each process, the performance for galleries with remote media sources was very poor. We’ve tweaked the manager thumbnail check to only run when you use the File media source type to work around this.
Finally, we’ve also implemented some sanitisation for data retrieved from YouTube. If the video name or description included invalid characters, those should now be filtered out properly.
