Hi wardog,
I'm not entirely sure what you are trying to do. If you just want to echo a resized image in the template, then you should be able to do this without your ImgResize function.
If you need to resize in the PHP with a custom function (like you are trying to do now) then your function is wrong.
Use (in you're 'Galeria' class):
function myResize($width = 50, $height = 50) {
return $this->Image()->getFormattedImage('resizeRatio',$width,$height);
}You should then be able to use 'myResize' as a control in the SS template.
That should sort out your problem.

I think I did not understand very well .. I am making a template to create a gallery using slidershow
but I can not do resize the image to the thumb ... and I read the documentation but I can only do when DataObject use or do not understand how to make the image resize what you need so as it is generating resize the image and get the url of the image with the display so that it can resize -
