Changing the watermark icon

Hi,

This is sridhar, I am using Lazyest gallery,its working very well. But my problem is while doing watermark for lazyest images, i am having pre defined icons only…
But i need to upload my logo…
Is there any way to change the icons of lazyest watermark..

Example: The icons are 1.Academy,atm,books,wheelchair,computer…
I need to change this icons to my own icons or my logo..

Thanks in advance..
