Hi Jain
First of all create a separate column in your backend to store the image name along with extension{Suppose imgName}
1. Copy your images into <Project Name>\src\mimes\Components\<your component>\
2. Create a Node Attribute "Image" with cardinality Property as 1..1
2)a Create 2 value attrubutes
i) imageAlt [Calculated Property as TRUE]
ii) imageSource [Calculated Property as TRUE]
now in your NWDS do the following
2)b Bind the imageAlt attribute to ImageUIElement's alt
2)c Bind the imageSource attribute to ImageUIElement's source
tmpImageName=wdContext.CurrentContextElement.getimgName[this statement retrieves the image name from back end
tmpImgaeAlt=wdContext.CurrentContextElement.getEmpName[this statement retrieves the name from back end where in
we use this name as the tooltip for the image]
wdContext.currentImageElement.setImageSource(tmpImageName);
wdContext.currentImageElement.setImageAlt(tmpImgaeAlt);
this will increase db retrival speed.
hope this will solve your purpose
