Question:
I'm trying to post pictures.
Some goes through and some rejects as error.
Is there special way?

It's probably too large. Make sure that you crop any phto before posting.

That's a simple answer, I'm not good at computer, reducing to small picture is something I can handle, Thank you,

I tried to upload with reduced size but it rejected as Error or invaild extension.
Some of the picture got posted and some rejects.
I tried for many hours with many different ways but no luck and now I'm almost at give up stage.
