Images not showing when using webproxy

I have problems with images not showing when i use webproxy for blocking websites. The sites that i have accepted will open but the images are not showing.

Anybody have a solution? Using RB433 with Ros 5.24 and also tried with 5.23

Do you have some rules like this in web proxy:

/ip proxy access
add path=.jpg action=deny
add path=
.jpeg action=deny
add path=.png action=deny
add path=
.gif action=deny
?
