Getting image data as a variable

| The problem lies in that I want to use database explicity for putting up
images on a blogsite (i don't want to use the filesystem what-so-ever)
(mostly to save myself from having issues with duplicate filenames, and
when I delete one, both goes.)
Image is loaded via a web-form, and are to be resized. Currently I save
the images on a folder which everyone has write and execution-access to.
Images are resized via the imagecreatetruecolor() and
imagecopyresampled(), and then written to the filesystem. After that
read into variables, which in their turn is written into the database.
Is there any way for me the skip the filesystem-bit?
Help much appriciated.

Yes - don't write them to the filesystem. You can use imagejpeg to return
the actual image data as a string, which you can then put in the database.

(this isn't a lecture but an offer of help: making so much work for each
and every request is not a great idea - if you can do the work once when you
add/remove images, your web server would thank you :) I'm not having a go,
I just don't see the benefit - it's pretty easy to make scripts reliable
enough to overcome missing images (should that ever happen) and duplicate
filenames... if you tell me what your actual concerns are, maybe I can help?
I worked at a company that had several hundred gigabytes of images, all
indexed by database, so I have a bit of experience with this, not that I'm
saying you don't :))

Yes, you can work directly on the $_FILE array as once the image is
uploaded it is already on the filesystem in a temporary folder.

| Sure I can do this, but I want to resize images before saving them into
the database, therefore, working with the $_FILE does not work.
Any other ideas.

How? I've tried this a numerous times, and currently I write the images
to a temporary file, and then reads the data from that file (and puts it
in the database).

The work is done when uploading a image to the server, and then saved
into the database. This is to make it much easier for me to backup the
site. Since I don't have local access to the site, and still want to be
able to write bakcupscripts, so that I have a backup of the site every
now and then. This way, all I need to do is keep a working copy of the
code, and then take a backup of the database every now and then in order
to keep my backup up-to-date.
