We would've asked you for piccies inevitably - see how much restraint we showed?
If you pop into the section for new joiners, there's a sticky at the top of the board which will take you through the process. But I cant be doing with them destructions which are too sophisticated for me (for that, read that I'm inept, and cant follow basic instructions) , so you could use Tiny pics - you dont need an account and it's free -
http://tinypic.com/Leave the setting at "default" initially. Once you've selected your picture (browse your folders for the pics you want to use) it will upload one picture, then click on the code for forums and cut and paste into your message on Purrs. That should work.
How long have you had your furkids, and did you get them together, or at different times?
