        //Keyword “this”: references current gallery instance 
        //curslide: returns DOM reference to current slide’s DIV (ie: try alert(curslide.innerHTML) 
        //i: integer reflecting current image within collection being shown (0=1st image, 1=2nd etc) 
    } 
})

</script>

<div id=”simplegallery1″></div>

 

Now carefully make these changes:

  1. Resize all your images to a fixed size. To change the image size edit 300, 200 where 300 is the width and 200 is the height. If your images are of bigger size then they will be clipped rather resized. So its better that you manually first resize your images in Photoshop and then proceed.
  2. Upload your images in blogger and then replace  IMAGE LINK 1, IMAGE LINK 2 ,….,so on with your Image links in that order.
  3. Replace # with the Page Link. The visitors will click the image to land on a page so mention the URL of that page. If you don’t want to link the image then simply delete #
  4. Replace DESCRIPTION with some information about the image. This image decription will appear at the top when a user hovers cursor on it. If you don’t want to write any description then simply delete  DESCRIPTION
  5. If you don’t want the images to play automatically then turn off auto play. Turn trueto false.
  6. To change the time interval between next and previous slide then edit 2000
  7. That’s it! You are all done!🙂

You can do a lot more but I am not sharing every thing here for simplicity. Yes you can change its entire look, colors, fonts and all. If you need any further customization then just post your query and I will reply the earliest possible.
