Hi, this is my experience for uploading my son's pictures last night for your easy reference.
Steps:
1)Upload the pic to the Facebook;
2)Download it to your computer from the Facebook;
3)Upload it to the Forum; and
4)If the size of the pic is still over 200kb, screenshot your pic in your cell phone, corp the bird, save it to your Gallery and then repeat Steps 1-3.
Honestly speaking, the quality of the pics are far from satisfaction, but I consider them quite successfully since they were taken by a 7-year old boy who has used the camera for 3 times only.
Hope the above experience is useful.
Have a nice day
