There's detailed documentation here including an API reference:
http://www.openmicroscopy.org/api/omeis/

The universal API for the image server is GET and POST requests sent  
using HTTP.
As for code, it depends what you're issuing the request from.  You  
can do it using a form specified in pure HTML for example, using no  
code at all:
<form action="http://localhost/cgi-bin/omeis"
	enctype="multipart/form-data" method="post">
<input type="hidden" name="Method" value="UploadFile">
<input type="submit" value="Send">
<input type="file" name="File">
</form>
The browser will ask the user to select a file to upload.
An oddity here is that the file must actually be the last thing sent  
to the image server, so it has to appear last in the form.

You can do it on the command line using curl (similar to wget) like so:
curl -F Method=UploadFile -F File=@/home/igg/images/cb_1.r3d http:// 
localhost/cgi-bin/omeis

Perl has several modules for doing HTTP (LWP or libwww-perl among  
others).  If you're writing an extension to the OME back-end, you can  
simply call:
	my $file = OME::Image::Server::File->upload($localFile, $repository);
Which returns an OME::Image::Server::File object given a path in  
$localFile and an optional Repository attribute (an instance of the  
Repository ST).
Or, you can call
	my $fileID = OME::Image::Server->uploadFile($repository,$filename);
Here, the repository attribute is not optional, and the call returns  
the raw file ID (not an OME::Image::Server::File object).  You can  
always get the default repository like so:
	$repository = OME::Session->instance()->findRemoteRepository();

There is OME-Java code to do this as well.  All of these are very  
very thin layers on top of standard libraries that let you issue HTTP  
requests.  The OME back-end uses libcurl internally with our own perl  
bindings for it (perl2/OME/Util/cURL.pm).
