Wrong code for <img src>

Hello everybody,

First of all, I would like to apologise if my English isn't very good, I'm french but I'll try to be understandable.

I'm using CKEditor on a personal project, with PGRFileManager for uploading images.
I'm trying to print a picture in the content of an article.
The upload is working, but the picture doesn't appear when I print the content of the article.

If I look the HTML code which is generated, I see :

<img alt="\&quot;\&quot;" src="\&quot;http://acturevue.com/Acturevue/admin/upload/pict/pict-img18744.jpg\&quot;" style="\&quot;width:" 150px;="" height:="" float:="" left;="" margin:="" 10px;="" \"="">

I think the problem comes from the double " before and after the URL of the picture.

How can I modify this code ?
I've been searching for the solution for 3 hours, but I don't find it.

Does somebody have a solution ?

Sorry again for my bad english, I hope you can at least understand me.

Thanks,
Grégoire C.
