When you visit the the 4rums you will see 1 great
effects for image, yes you can
zoom it smaller or larger. It also helps your blog/site to load faster if the
images are too large.So today i will introduce you this tip for
blogspot by js file - it's called
FancyZoom.
Look at this photo :

1st , log in
Blogger > Layout > Edit HTML then add this code below before </head> tag:
<script src='http://zendersto.110mb.com/FancyZoom.js' type='text/javascript'/>
<script src='http://zendersto.110mb.com/FancyZoomHTML.js' type='text/javascript'/>
Ok now next step, you have to change the <body> by <body onload="setupZoom()"> instead
Save! You have already created zoom effect for images.However ,to zoom image you have from now , you don't have to use the tag <img src="Image link" /> to add image anymore , but you have to use this new form :
<a href=" Image link "><img src=" image link " width=" 300 " border=" 0 " height=" 200 " />
Note:
Image link : support jpg, png, gif ...
Width : thumbnail width.
Height : thumbnail height.
Border : thumbnail border.
For example :
<a href=" http://img.tamtay.vn/files/_Andy_/photos/78996/47a46afa_when_the_love_falls2_resize.jpg "><img src=" http://img.tamtay.vn/files/_Andy_/photos/78996/47a46afa_when_the_love_falls2_resize.jpg " width="300" border="0" /></a>
