It may depend on how the software you're using to rotate the pictures
works. I had a similar problem using Canon's ZoomBrowser software. You
can read the explanation below, but the most straightforward thing is to
check the permissions of the files that you can't rotate.
Because you have XP Home, you'll have to do this in safe mode, and as a
user with administrative privileges. Right-click on a file, select
Properties, and then the Security tab. If you compare the permissions
for a file that does not have the problem with one that does, you should
see the difference (probably "Everyone" does not have modify rights to
the problem files). In the "Advanced" screen, make sure that the box to
"Inherit from parent the permission entries that apply to child objects"
is checked (this is the default).
Now, right-click the folder in which the picture files are stored and go
to the Security tab. Click the "Advanced" button. This time, there
should be a second box to "Replace permission entries on all child
objects with entries shown here that apply to child objects." Check this
and OK out (note that this operation can't be undone). See generally,
http://support.microsoft.com/kb/308418/ and
http://support.microsoft.com/kb/308419/
Apparently, the way Canon's "ZoomBrowser" image filing/handling software
works is that when the EXIF information from the image file on the
camera indicates that the picture has been taken in the vertical format,
the software initially stores the file in C:\Windows\Temp (or other
temporary directory) in the usual landscape (horizontal) format, then
rotates it, and stores the rotated version in the intended target
directory.
The problem is that the Temp directory -- where the file is initially
created -- is not shared (who would think to share the Temp directory
!?). And, according to KB310316, "By default, an object inherits
permissions from its parent object, either at the time of creation or
when it is copied or moved to its parent folder. The only exception to
this rule occurs when you move an object to a different folder on the
same volume. In this case, the original permissions are retained."
Thus, even though the file appears to be in a folder that has the
"shared" permission set, it has inherited the original "do not share"
permission from the Temp directory in which it was created.
