> Hi, > i need to prevent someone from just replacing the images in my applet. Is there a way how i could check for example the file size of an image from my applet? Or maybe there is a way to check the RGB-values of some pixels in the image? I could then define some final Values for the file-size(or RGB values) of my images and then just compare them with the size of the loaded images...(and if they are not equal for example just display a black rectangle, instead of the applet ). Can someone help me??? > Please mailme if you can( i_love_u_all14@hotmail.com ). > Thank you in advance, > sincerly Ilya Shabanov You can use the FileInputStream object and call the function available() which returns the number of bytes.
