Thank you meanie for the translations.
I understand that the first tab is for Lossy compression, such as *.jpg
It has a scale which is adjustable when saving as a .jpg (0% - 100%)
The dropdown has 3 selections:
1.

(1bit) (does this equal 16 color palatte?)
2. 256?? (8bit) (I'm pretty sure this equals 256 color, 8bits)
3. Not sure what this means, I'm hoping 16 or 24 bit (65,000 or 16 million colors)
I haven't used the Transparent tab yet. I need the correct graphics file format to use that feature.
