SecurityException: Unable to create temporary file

Perhaps you aren't allowed to create a temporary file in the specified
directory:

<http://java.sun.com/javase/6/docs/api/java/io/File.html#createTempFile(j
ava.lang.String,%20java.lang.String)>
<http://java.sun.com/javase/6/docs/api/java/io/File.html#createTempFile(j
ava.lang.String,%20java.lang.String,%20java.io.File)>

Which directory is used when load an Image with [ImageIO
#read()]?

I suppose it would depend on the directory you specified in your call to
read().

My applet is signed?

I do not know if your applet is signed. Even if it were, you would still
require permission from your operating system to create a temporary file
in whatever temporary-file directory is specified in createTempFile():

SecurityException: Unable to create temporary file

It looks like the default temporary-file directory is specified by the
system property java.io.tmpdir.

try putting
javax.imageio.ImageIO.setUseCache(false);

before you read the image.
