Dompdf doesn't show images with a space in path

Hi and congratulations for this great module.

I use print module for generating a pdf version of a catalog views. I use imagefield + imacache and all is working very well, all images are shown in pdf, (I have "remote file access" set to "true" in dompdf_config.inc).

Recently, I use "powertoy resizer tool" for resizing images in a smaller and lighter version of images; this tool creates a copy of original image to a reduced version (example: "image.jpg" to "image (small).jpg").

The problem is when I upload the new reduced image to a node; the image is showed in the normal view but is not showed in pdf version. After testing and searching about it, I know the only problem is a consecuence of the "espace" in the name of the image. For some reaon, dompdf can't find the new image with a space.

Example:
http://www.mysite.com/files/image.jpg ----> pdf version works perfect
http://www.mysite.com/files/image (small).jpg ---> pdf version doesn't show image

How could solve this issue? It's strange because imagecache handle perfectly an image with a espace, and imagefield, too.

Please, could someone help me?
Thanks in advance
