How can we pre-load an image before and after the current image?

[awartani]

Hey all,
Great work!
How can we pre-load an image before and after the current image? I read in the threads that was not part of designing this library, can we understand why? and it would be great if you can explain in any level how can somebody else implement it and if you would be open to merge it if it looks good?

Thanks!
