URGENT : Please HELP : Loading a first image too slow

Question

Hello,
I want to load an image to save it just before in a JPG format so as to obtain finally a byte[] array of this JPG image result.
So, to do it, I tried to load my Image from different ways but I have always a strange comportement... My problem come from the reading :
First, I use the imageio classes...
FileImageInputStream fiis = new FileImageInputStream(file);
BufferedImage input = ImageIO.read(fiis);
And then, I use the oldest method :
Image image = new ImageIcon(file.getAbsolutePath()).getImage();
BufferedImage input = new BufferedImage(image.getWidth(panel), image.getHeight(panel),BufferedImage.TYPE_INT_RGB);
and also :
Image image = new ImageIcon(file.getAbsolutePath()).getImage();
BufferedImage input = toBufferedImage(picture);
But finally, I understood my problem is that the first time I load an image (no matter the format, JPG, BMP, TIFF... or other) the loading phase is very slow and lasts at least 30 sec. But then, every loading that I do will gonna be really fast. (No more than 1 sec.) It's look like if the first time there was a kind of dinamical alocation or something like that.... but I tried to find some configuration parameters to set it... But without success. :-(
If someone could have an idea to suggest me... it would help me very much.
Thanks in advance for your help,
Anthony

Please someone can help me ?!? A suggestion ?
I have tried today one more time to resolve this issue... but without success... Anything I do with the loading of an image... by imageio or other ways... it's still the same problem... the first time I load an image, it takes me 40 - 50 sec to load it and after this first load, it is very fast with others... and with every formats. It's not a question of format but of memory allocation, I think... but I'm not sure...
PRECISION : I work with an applet, is there something to configurate to allocate some memories or another thing ?!?
Thanks in advance for your help, I really need it just right now... I have to finish this job extremly fast !!!

Anthony
