Thank you for your reply krileon.
With your information, i had test all acces of ajaxpoint field. Actually, its not totally working. Pictures and field's result are actived in frontend but i cant increment field by profil area.
Caution => ? (I have increment my field por my exemple '10')
1 - In my option field, when i check Public Access & Member Acces, i see the result of field with pictures.
When i check Admin Acces, i see result of my field but pictures up & down disappeared.. In this two situation i can't increment. (Im owned right)
2 - I have a display bug we same configuration
3 - i have see a display bug with same configuration between user's profil and admin's profil, look this !!!
Finally, i miss to say you that i use CBPP... and this HTML editor... I have test many configuration and i have see the display bug cause by CBPP...
But AjaxText is working on !
