How to add Image in a form?

Respected Sir,

        I have divided the page into different frames.In the top frame and middle frame i want to display different images in each form. I searched your forums and threads to load images in a form. I could not find any source which showed me how to load an image in a form. So i edited the sky_blue style sheet and added an jellybean.jpg image source. Now i am getting jellybean.jpg image in all my forms by default because of the style sheet.Please tell me how to add an image in a form. i know for a fact that my approach is wrong. Please help me out. 

Regards
Kiran.S

Hello
We are recommend to use an image as a custom item.
Creating of such item is here:
docs.dhtmlx.com/doku.php?id=dhtm … ustom_item

If you want background image to just one form, you need to set id for the form container (in my case it is div with id ‘myForm’)and apply the next css rules:
#myForm .dhxlist_base{
background-image: url(“img.jpg”)
}
.dhxlist_base_nested .dhxlist_base{
background-image: none !important;
}
