I am a wordpress newbie, but slowly getting into it. I was wondering about the new image gallery system, and integration with Galleria plug-in. I love the functionality and look, however, is there a setting that will cache my re-sized and optimized images, (thumbs + main images)? If I have more than 20 on a page, it seems to take way to long to load. Is scaling the images before upload would be the only solution?
