How to upload photos to a post.
1) After writing your post, underneath the message box, click on Additional Options.
2) Next to Attach, click on the 'Choose File' button.
3) Select the photo file you want to use from my computer's hard drive (it must be less than 300k in size).
4) If you want to add another photo, click on (more attachments) and repeat the procedure.
5) Click on Post and the message & photo should be displayed.
You just add the photos and they are displayed at the end of your post but you don't choose where they go in the post. You can add a maximum of 4 photos per post at present, although we can easily change that if you would like more.
Have a go, any problems, just let me know and I will advise.
