Hello, Joel,

thank you for your remark. I am fully aware of your troubles, but working
only from internet cafes in Paris, I cannot help you and me now. I will be
able to redress and republish my pictures only in August from Prague.

Meanwhile, can you give me advice about software and modes that shall I use?
I tried higher compression ratios for these JPG's, but the quality suffered.
And as these pictures are not the best even uncompressed (it was a bit
difficult to take them in an unsuitable room, deep behind the glass), I
wonder, how to diminish them and not to degrade them too much.


Thanks, Jan Kalivoda
