GZIP compression

Hi and thanks for a great platform. I have just added GD to my site http://arlingtonporchfest.org and I’m excited what it can do. Today I installed GD Booster. Enabling it was a little quirky but seems OK. I’m hoping you can please help me with the GZIP compression. I added the lines to my .htaccess, but it seems to me that my Bluehost server is missing mod_deflate / mod_filter. I edited my php.ini but I’m not sure I did it correctly.

when I look at php_info() I see
zlib support enabled
zlib.output_compression off (both master and local)

Here are the relevant lines (I think?) in my php.ini

; You can redirect all of the output of your scripts to a function. For
; example, if you set output_handler to “mb_output_handler”, character
; encoding will be transparently converted to the specified encoding.
; Setting any output handler automatically turns on output buffering.
; Note: People who wrote portable scripts should not depend on this ini
; directive. Instead, explicitly set the output handler using ob_start().
; Using this ini directive may cause problems unless you know what script
; is doing.
; Note: You cannot use both “mb_output_handler” with “ob_iconv_handler”
; and you cannot use both “ob_gzhandler” and “zlib.output_compression”.
; Note: output_handler must be empty if this is set ‘On’ !!!!
; Instead you must use zlib.output_handler.
;output_handler =

; Transparent output compression using the zlib library
; Valid values for this option are ‘off’, ‘on’, or a specific buffer size
; to be used for compression (default is 4KB)
; Note: Resulting chunk size may vary due to nature of compression. PHP
; outputs chunks that are few hundreds bytes each as a result of
; compression. If you prefer a larger chunk size for better
; performance, enable output_buffering in addition.
; Note: You need to use zlib.output_handler instead of the standard
; output_handler, or otherwise the output will be corrupted.
zlib.output_compression = on
;zlib.output_compression_level = -1

; You cannot specify additional output handlers if zlib.output_compression
; is activated here. This setting does the same as output_handler but in
; a different order.
;zlib.output_handler =

I would be very grateful for any tips thanks!!
