MultiCore MultiThreading and preload more pictures are needed.

[Yi Zhou]

When loading a large number of JPG files—each exceeding 10-20MB—the process is very slow, often taking 2-3 seconds, even though multiple CPU cores/threads remain idle.

Instead of using multi-threading to load a single image simultaneously, a better approach would be to preload more images, with each image handled by an individual thread. This way, we can fully utilize the user's hardware resources, given that both CPU and RAM are ample.

The maximum number of preloaded images can be user-defined, either based on the number of files (e.g., 100 files) or available memory (e.g., a 5GB limit), the limitation can be both.
