It was not so easy for me to understand how to paste a photo on the forum, but then I got some wounderful explanations of the procedure from Marie with Mayoa and Quidam. It may be that someone else may be in the same situation (i.e. not on so good terms with their's computers ), so I wanted to share the detalied procedure fo what Marie wrote to me with you other users of the forum.This is what you must do to put one photograph on the forum:
* first you have to click on "héberger une image" (= browse your image)
* then you arrive on a site : servimg.com you have to enter your e-mail adress and password.
* click on "envoyer une image" and then on "parcourir"
* chose your photograph in your documents, and then click on "envoyer"
* the computer will take a moment for charging the image...
* one page will appear with a small reproduction of your image and with a lot of information on it.
* copy the second url in the category "BBcode", and then paste it in your message.
When you're on the site servimg.com, you have four sections : image; BBcode; Htlm and liens directs.
In the section BBcode, you have two under-sections : miniature, and image. Above "image" you have a sort of adress, the url (il begins by url). You have to copy this adress and then to paste it in your message. Then when your message is sent, your image will appear.
That's all.
Good luck!
