Thanks everyone for the replies. I've managed to simplify this process
greatly. now instead of 8 or whatever intermediate files i now have 2..
here's the code i simplified it into:
convert -size 320x320 DSCN9319.jpg \
-thumbnail x320 -resize '320x<' \
-gravity center -crop 320x320+0+0 +repage \
-compress None cut_to_fit.png
convert -size 320x -background none -gravity center -pointsize 50 -fill
white \
caption:'TITLEE Blah BLAH' -shadow 70x8 -composite \
caption:'TITLEE Blah BLAH' -shadow 50x4 -composite \
caption:'TITLEE Blah BLAH' -composite \
-compress None text.png
convert \
cut_to_fit.png -composite \
text.png -gravity south -composite \
-bordercolor white -border 6 \
-bordercolor grey60 -border 1 \
-background none -rotate 18 \
-background black \( +clone -shadow 60x4+4+4 \) +swap \
-background white -flatten \
-thumbnail 160x160! \
-quality 85 \

This is the code written in bash for testing and ease of looking at it.
I'm wondering if it can be simplified into just one command? The problem
i'm running into is that the text needs to be layered ontop of
eachother, if i try to layer it over the full image it won't line up
properly with -gravity south, as the blurred text is larger than the
non-blurred text. The non-blurred will end up lower in the image than
the center of the blurred text if that makes any sense. Therefore i have
the above solution making a seperate image where they can all be
-gravity center and then taking that image and composing it over the
larger image -gravity south.
Right now it takes ~ 2.4 seconds per image (depending on the size, most
are my cameras default 'fine' quality). This is a big improvement over
the old process which took 4 seconds for the same image. But i'm hoping
it can be improved even more.
My script does cache images, it only generates them once (unless i clear
the cache) But i will still like it to be faster if possible.
Thanks for all the help so far,
Jeff

I took a look at the above and most of it seems fine. However
You can combine multiple convert commands together.
Each convert command at the end has a single image. Rather than
save it to a file, you can just continue processing that image in the
same command.
The only exception to this is if the code needs to extract some extra
data from a generated image, before proceeding. That does not appear to
be the case.
Even the 'composite' command can be turned into a convert operation.
All the lines givem appears to be a near direct extraction from IM examples.
So none of them appear too difficult.

I would however start by re-adding the line by line formating
to make the processing steps easier to see...
The last two for example can be combine as..
convert '$label_fancy' \
-bordercolor white -border 6 \
-bordercolor grey60 -border 1 \
-background none -rotate $randomnumber \
-background black \( +clone -shadow 60x4+4+4 \) \
+swap -background white -flatten \
-resize 250x250! -strip -depth 8 -colors 256 \
-quality 85 -compress None \
'$newPath'
Removing the need for '$poloroid_single' intermedite file.
Perhaps a seperate script can be used for the image processing, to
simplify the quoting that PHP is adding to the above.
