Hello, holas;
there is another "dirty" way to show a medium image and display it in its original dimensions in a new window, using a javascript code.
Hopefully, there is a very more cosmetic way here:
Lightbox 2.
Let's say you need to have your images restrained to 520 pixels wide because of your template's definition. For JPG images, you will have to set your
templates/your_template/media/jpg.html to this, using Lightbox 2:
<!-- Template file for JPG Files-->
<div align="center">
<a href="{media_src}" target="_blank" rel="lightbox" title="{image_name}"><img src="{media_src}" border="1" alt="{image_name}" width="520" /></a>
</div>
You can do the same thing for other image formats.
Desde luego, paisano, no te apures. Si lo necesitas, puedo ayudarte para ponerlo en tu sitio. Contactame entonces.
