For that to happen, the file has to be in the top-level directory of one of 
your layers listed by BBPATH, which rarely happens, as proper layers have at 
least a minimal directory structure, such as conf/, recipes/ etc.

On the other hand, if you really want that file to be included from another 
layer, which is higher priority or listed earlier, then you would need to do:

require recipes-core/images/core-image-minimal.bb

I haven't tried that, but I believe it will be the same as w/o ./
