Topic: mime type png problem

[Rob]

Hi,

I put a png picture on my website( SME 5.5) , but only IE can
display it. Other browsers can't, because the mime type is "text".

I have also been playing around with php, and that does seem
to work properly, eventhough both php and png are not in the
mime-types files, /etc/mime-types and
/etc/e-smith/templates/etc/mime.types/*

Should png not be in the default mime-types list, and what about
php? Or is this defined somewhere else?
Is there a reason for limiting the amount of mime-types?

Thanks,
Rob
