well, a quick google turned up this thread. I've tweaked the applescript I found there a bit. Open the applescript editor, paste in the following code, and save it as an application. It will create a new droplet app; drag and drop your files onto it and they'll be converted. You're going to have to let it work. Pages needs to be frontmost while the script runs, which means you won't be able to do anything else until it's done.
I suggest you convert them to pdf files rather than word files (I've set it up to do pdf by default). Everyone can open pdfs (not everyone has Office installed on their machine), pdfs will deal with the pictures and formatting properly, and (unlike Word) pdfs can't be edited easily.
on openfileList
-- change this line to the extension of whatever output file you want.
set newFileExt to "pdf"
-- change this line to point to the folder you want output files to go to. preset to desktop folder.
set savePath to path todesktop folderastext
repeat with thisFile in fileList
set thisFile to thisFile as text
tell application "System Events" to tell disk item thisFile
set {fileName, fileExt} to {get name, get name extension}
end tell
set newName to text 1 thru -(1 + (count of fileExt)) of fileName
tell application "Pages"
activate
-- tricky: apparently Pages is smart enough to create the correct file type based on the extension
set newFileName to savePath & newName & newFileExt
set x to makenewdocumentwith properties {path:newFileName}
openthisFile
