Dries, great catch! What prompted this originally was that the
screenshots on the theme page didn't have dimensions, didn't realize
that index [3] returned this. Anyways, this patch fixes the screen
shots and adds widths/heights.

Function theme_image() doesn't actually return a width and height for an
image like it claims to do.

Ok patched attached, which fixes this issue. Also, included a patch for
system.module which sets the screen shots to 'TRUE' so image dimensions
will also be outputted there as well (which they should be!).

Used the patch, and did a quick test. Worked well for me. +1.

I don't see why this patch is needed, "theme_image" returns a img tag
with the width and height set if $getsize = TRUE.
$node->body = theme('image', file_create_path('druplicon.png'), 'no
alt', 'no title', array(), TRUE) .
file_create_path('druplicon.png'), 'no alt', 'no title', array(),
will return:
<img src="files/druplicon.png" alt="no alt" title="no title" width="88"
height="100" />
<img src="files/druplicon.png" alt="no alt" title="no title"  />
(if druplicon.png is copied to the files/ directory).

I don't see what you are fixing...

You are right about the use of theme('image') in system.module though.
The "false" should be "true".

Well the actual code in theme_image() returned this:

return '<img src="'. check_url($path) .'" alt="'. check_plain($alt) .'"
title="'. check_plain($title) .'" '. $image_attributes . $attributes

There is *no* mention of the $width and $height variables that are
assigned above, not used at all. I checked images in the themes
directory and none had this information, unless I was missing something
obvious, I see no way that is being generated... nothing in the above
img src about it.

Taken from http://php.net/getimagesize: "Index 3 is a text string with
the correct height="yyy" width="xxx" string that can be used directly
in an IMG tag.".  $image_attributes contains this information.  Marking
this fixed.  Please reopen if not.
