I had a spell when that happened - everything seemed to go all right until the waiting for DS bit and then it would stop.
I left it a couple of weeks and it started working again.
Computers, eh? Don't you just love them!?
My connection is very slooow. Photos will not load until I reduce the size to less than 200kb. Emoticons won't load at all.
I use Format Factory to resize photos.
Good programme formats audio, video and photo from and to any format and size. Used to be a free programme.
If you can Jettejette, try resizing and posting. If it works great. If not it's something else...sorry.
