Judy, I know just how you feel! I had this happen to me the first time I tried to post a photo on the new website. Please try again.
Try this as an alternative - but it might not work either. I use a Mac and things are slightly different but I think the principle is the same -
1. drag the image you want to post to your desktop. It should be there with letters and numbers below it including jpg or something similar.
2. Click on the attachments box below where you are typing your reply, which should open a drop-down menu. Find your desktop and click on it. You should now see the image from your desktop.
3. Click the image to highlight it and then click 'open' at the bottom of the drop down menu.
The file name/numbers, letters should now be appearing in the attachment box.
4. Now click 'insert' and that same file should appear in the typing box. When you have finished typing what you have to say click submit.
This is what I do and it has been working for me. If anybody has any other suggestions or if you think it is different on a PC please let Judy know.
I hope it works this time.
