Amrit try this: <html> <head> <script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script> <script type="text/javascript"> function setAllImageWidths(newwidth){ $('.myimage').attr("width", newwidth); } function undoSetWidths(){ $('.myimage').removeAttr("width"); } </script> </head> <body> <img src='http://www.cardsunlimited.com/largeimage/ChristmasRobin.jpg' class="myimage" /> <img src='http://louisey.files.wordpress.com/2009/10/red-tractor.jpg' class="myimage" /> <p> <button onclick="setAllImageWidths(100);">Image widths 100</button> <button onclick="setAllImageWidths(1000);">Image widths 1000</button> <button onclick="undoSetWidths();">Original width</button> </p> </body> </html> ... So what you do is set the images to a generic label e.g. class="myclass", change the attributes of myclass and youre good to go. you see the problem is JS doesnt come with a getelementbyclass for the obvious reason that it would have to get a multiplicity of elements whereas an id is just one element, so it makes sense to have a getElementById. However someone has written a getElementByClass which is here: http://forums.devshed.com/javascript-development-115/javascript-get-all-elements-of-class-abc-24349.html and ofcourse, jquery has it aswell, which you'd be alot safer using. have a read of: http://docs.jquery.com/How_jQuery_Works Happy coding, Alex
