Hello,

i don't know why , i can upload a pic from a form using ckeditor

/app/download/plugin_ckeditor_upload.upload.a7dc4103618b052d.57494e5f32303230313030315f31365f35325f31305f50726f2e6a7067.jpg

i submit the record is registered, , i visualise the view , the code source is correct

<img src="httpxxxxx//LETTER/download/plugin_ckeditor_upload.upload.a7dc4103618b052d.57494e5f32303230313030315f31365f35325f31305f50726f2e6a7067.jpg">

and the pic is not displayed . If i use an existing  pic in the directory uploads  from a table with an another name  like mytable.myfield.b77ad521b8552f22.43656c6c42696f6c6f67792e6a7067.jpg

it works

why ? thank you

Note : if i browse the pics with ckeditor, i see the names but they are not displayed
