Stretching background image in panel

[prajakta.gharpure]

Hello all,

I am using a panel whose background image is set. Though I dont want the background image to get tiled but it should stretch inside the panel. How much ever small the image is, it should get stretched and fit to panel according to the size of panel.

How do I get this functionality??

Please note that there is a specific reason that I want to stretch the panel background image and I cannot use any <img> tag.

Please do let me know the suggestions.

Regards,
