Cute!
To post smaller pictures:
Right click on your photo before you upload it. Then click on "resize photo" from the menu. Then the option for small, medium and large will come up. Always check on 'small'. Then a new photo will appear beside the old one, that says the photo number and 'small'. You can then upload the small version.
If you ever have trouble posting photos or they take too long, make them small and they will upload quickly and with no problem. This site likes small photos... whereas Ebay likes large ones.
