You might consider a slight hack to change Special:Upload from being 
open to all users to being open only to administrators. This would save 
the trouble of rewriting a separate tool (unless of course you want 
one, say to do mass uploads easily).

Find this line in SpecialPages.php:
	"Upload"            => new SpecialPage( "Upload" ),
and change it to:
	"Upload"            => new SpecialPage( "Upload", "sysop" ),


And to hide the link from the sidebar, change this bit in 
SkinPHPTal.php:
	if( $this->loggedin && !$wgDisableUploads ) {
to:
	if( $this->loggedin && !$wgDisableUploads && $wgUser->isSysop) {

Here's what I have sitting in my 1.3 test wiki (it's just one image):
*************************** 1. row ***************************
        img_name: VegTomato.jpg
        img_size: 2438
img_description: dddd
        img_user: 1
   img_user_text: WikiSysop
   img_timestamp: 20040928234934

img_user is a key to user_id; img_description is freeform text up to 
255 characters. It's displayed in the revision list when you look at 
the image page, and is formatted in the same way as edit comments. 
img_timestamp is in the same format as our other timestamps, 
YYYYMMDDHHMMSS and should be in UTC rather than local time.

img_name should not contain spaces; as with page titles, use 
underscores. If you want non-ASCII characters in filenames, be sure to 
use the encoding that matches what the wiki is set for (either UTF-8 
unicode or 8-bit ISO 8859-1). If you're not on a standard Unix/Linux 
filesystem there may be funky restrictions on non-ASCII filenames. 
(Latin-1 names will not work on Mac OS X / HFS+, I haven't tested on 
Windows.)

The file is at images/b/bf/VegTomato.jpg; the subdirectories are 
respectively the first and first two hexademical digits of the MD5 sum 
of the file name (in this case the full sum is 
bf79999a6a7fe8554814185369f7017d). They're not secret, it's just to 
even out the distribution so when you have 200,000 images uploaded it's 
not as unwieldy to do directory listings as it might be. :)
