hi deegoy418,

There r few reason why i followed my approach since
ie6 got issues when we change the image on hover or using javascript it downloads d image each time from d server and make d progress bar work so badly .
They said it is d bug :
http://support.microsoft.com/kb/293373

As my example will overcome the problem faced by us but i dont know y on postback if we dint move d mouse, still on d same image and if we click d imagebutton its not triggering postback

y it is ?

your Example dint worked on ie and also combined image is tds process now as all images are kept seperately

Thank u For Response .

Hope to see some brighter side of this issue soon
