This program will generate a html page with animated gif. You just need at least 2 gifs and use the program to set the time to display each image. Click on the "generate html" button and it will generate the code for you. Try out and see ..

This basic program can be used to generate html code using javascript for animating the images.
The duration of image cycle is in milliseconds. A html file will be generated as specified
Feel free to use this program to generate the codes. Cut and paste the "Generated codes" to any html file as required...adding my name somewhere in your html code will be much appreciated but this is entirely your choice
NOTE: The generated html file will overwrite the previous html file
