Hi,
I allow web application users to insert their own picture into database.
but i defined a max size limit 130 px width by 160px height.
so for that i determine the max ratio in case of picture does not have this
size.
after that i resize it and would like to store it to DB, however i have some
problem once it is resized.
here is my code :

$thumb is an image, so ho can i make it useful for pg_escape_bytea function
?
i do not want to create a tmp file on server and after load it.
I would like to do it stored image directly into DB on-fly.
thanks alot,

I don't know if there's a better way, but you could try output
buffering, so that you start it, output the image with imagejpeg,
imagepng, imagegif, etc. and then get the contents of the buffer.
