So some of the Malaysia SME , you have installed your openERP and ready to go and then you found out that your Web browser page , the image just do not get displayed and you are wandering why , here go the solutions for you ...
I was thinking is the openERP config file but not it wasn't it is the postgres config file.
so Go to postgresql.conf and replace the line
#bytea_output = 'hex' # hex, escape
bytea_output = 'escape' # hex, escape
and restart postgres server and refresh the web page and walla ... the images should be displaying properly LIAO (already) !
