This thread doesn't belong here, but I'll help you!

You can create an account on PhotoBucket or Zoto and upload pictures, then copy and paste the URL on Pet Talk. I perfer PhotoBucket because I think it's much easier to upload photos to and much more organized than Zoto. Or near the bottom of 'Submit Reply' or 'Submit Thread' click on Manage Attachments, and you can upload pictures there.

Hope I could help you out!
