I don't think it's possible to send images to a person via LJ though what you can do is upload them to your scrapbook (it's under the profile tab; click 'upload to scrapbook' and then just upload the files). Make sure the security is set to public otherwise I don't think I will be able to see it. Clicking the 'scrapbook' button under the profiles tab would bring you to your gallery where you can see all the pics you have uploaded so far. From there, just paste the urls of the pics here and wa la, you're done! Hope that helps ^^
