It would really, really help if we could see a picture.

On your iPod, download the Tapatalk app and navigate to the Frog Forum. Login, and then come to this thread. If you tap reply, at the bottom of the reply window there's a line of icons.

Tap the one with the mountain, next to the camera icon, and that will take you to your camera roll (NOTE: you have to allow the app to access your photos).

Upload the photo you want to "This Forum" (not "Tapatalk Hosted") and there you go.
