The 9.2 compression can be controlled via a regkey:

under: 
HKEY_CURRENT_USER\Software\Express Digital\EventLib\Options 
create a new DWORD value: 
PhotoEmail_Quality 
set the value type to Decimal (not hexadecimal) and set the value from 2 to 255 
2 is the highest quality, largest size 
8-12 are similar to what most cameras use for compression
