java thumbnail image program

Hello, I have some problem to make thumbnail" in JAVA. Our web site have some function to upload image file. When a user upload image file (jpg, jpeg, png, gif...), our system try to resize that image (size: 10 ~ 30Kb) and make thumbnail because big image cause big traffic. Almost image seems to be good. But i have two problems. 1) CMYK image cause big problem. program don't make thumbnail well because CMYK file is jpeg that a user make via Adobe photoshop and color table is different with general jpg.. i know. 2) quality is "low" Our source is as follow. 1) BufferedImage originalImage = [login to view URL](loadFile); int type = [login to view URL]() == 0? BufferedImage.TYPE_INT_ARGB : [login to view URL](); BufferedImage resizeImageHintJpg = resizeImageWithHint(originalImage, type, 555, 370); [login to view URL](resizeImageHintJpg, "jpg", saveFile); 2) private static BufferedImage resizeImageWithHint(BufferedImage originalImage, int type, int width, int height){ BufferedImage resizedImage = new BufferedImage(width, height, type); //BufferedImage resizedImage = new BufferedImage(IMG_WIDTH, IMG_HEIGHT, type); Graphics2D g = [login to view URL](); //[login to view URL](originalImage, 0, 0, IMG_WIDTH, IMG_HEIGHT, null); [login to view URL](originalImage, 0, 0, width, height, null); [login to view URL](); [login to view URL]([login to view URL]); [login to view URL](RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR); [login to view URL](RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY); [login to view URL](RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON); return resizedImage; } Could you do that?
