Hi Sebastian,
yes, that actually did help, thanks! I now can explain _why_ this is done.
We used uppercase constants here for all image/icon identifiers.
Maybe I will change to lowercase keys for these constants in the future, but
for now my question is answered perfectly.
Thanks again, keep the good work, ...topic closed (for me) ;)
