ShowImage read-ahead cache does not move along with navigation
|Reported by:||stippi||Owned by:||axeld|
When browsing large images, the positive effect of the read-ahead cache is immediately noticable, since the next two images after launching ShowImage with the first one will open instantly. However, the cache does not immediately begin to load the next images after navigating forward. After the first two images have displayed, navigating to the next images will always suffer the delay of loading them before they display.
