Size of image (file name)

Hello…
In a grid, I put a field of type image (file name).
If I put 0 in image heigth and image width, the image files are showed…
But if set some value (ex. 100 and 75, to set the size for all images), the images not are showed.
How i can do?
Thanks!!!

It’s rare…
for same image…
If the sizes are in 0, this code is generated.

<span id="id_sc_field_foto_1"><img border="2" src="<a href="http://www.dygjuguetesyregalos.com.ar/Fotos/00000001.jpg">http://www.dygjuguetesyregalos.com.a...s/00000001.jpg</a>"/></span>

And if sizes are some value (ex… 100 and 75), this code…

<span id="id_sc_field_foto_1"><img border="2" src="<a href="http://127.0.0.1:8090/scriptcase/tmp/sc_foto_751004710d3c7fbc933b0288a0d0fb06617b9.jpg">/scriptcase/tmp/sc_foto_751004710d3c7fbc933b0288a0d0fb06617b9.jpg</a>"/></span>

Note the src … the file is other… and not exist!!!
