Slide Show Applet

13 comments - Post a comment

/* Java applet to display sildeshow to images from a given folder in thumbnail form, images can be selected one by one and can be enable/disable slideshow of images. The thumbnail images are placed in slides folder, the download button(rectangle) downloads the images from the web server, hence a webserver is required eg : any webserver even tomcat webserver with download folder with images*/

/* Requirements
1. Name of java file : Sildeshow.java
2. Name of images folder : slides
3. Names of images 1.jpg, 2.jpg and so on upto 8.jpg.
3. Name of download folder in webserver : download
4. Download images given below and paste them in slides folder :
1.jpg2.jpg3.jpg4.jpg5.jpg6.jpg7.jpg8.jpg
5. Download images given below and paste them in download folder in webserver :
1.jpg2.jpg3.jpg4.jpg5.jpg6.jpg7.jpg8.jpg
