Request of Help

Hi,  
I like to thank You for the service that You are giving. I really 
appreciate it very much and is very useful for me and my fellows.  
Any way I have a couple of problems.  
The first is that I do not know how can I join the binaries files 
requested. Some times for the size, those files are split in several 
parts and I do not what progran to use in order to bring it back to 
the original form.  
The second is that I do not really understand the XIMAGE 
command. Please give a more readable example and the 
possibilities that it give.  
 Thanks for your attention in advance.
