I'm fascinated by your need for "siders". You must still be young 
with (you think) time on your hands. I'm a clapped out old wreck, so 
to me, your siders are merely stuff that slows down the drinking. 
Life is short when you;re getting towards the end of it! :D

I had to look up mojito. Never had one. I might think about having 
one or three some time ...

Thanks for the detail about JPEGs -- I was fairly well across that 
but you've added some detail for me.

Cheers, geoff
