GM Script: Prefetch Flickr Photostream
I wrote a new GM script to prefetch the prev/next photos of current browsing photostream. By doing so, when you click the prev/next photo of current photostream, the photo will show up immediately. The script will wait for the page and current photo completely loaded, then start to fetch prev/next photos in background. The default numbers of photos to prefetch are six, three for prev and three for next. You can modify the variable MAX_BUFFER['prev'] to increase or decrease the numbers. There's an indicator to show the prefetching progress, a red bar means in transfer and a green one means completion.
