Hi to all

I have a custom document type, with a custom transformation, im painting a zoom image to call the image field with the full size i can do it with the following instruction

<a href="<%# GetFileUrl("Imagen") %>" target="_blank">
<img src="~/App_Themes/mytheme/Images/zoomimg.gif" width="24px" height="22px" border="0" /></a> 

but it looks terrible and im trying to show it with the lightbox but i don´t know how someone can help me??

Thanks in advance
