Hello,
TinyMCE (v4) utilise REsponsiveFilemaanger pour les images.
Tu peux donc trouver des options sous :
\class\xoopseditor\tinymce4\external_plugins\filemanager
La doc complète se trouve sur
http://www.responsivefilemanager.com.
Tu pourras trouver notamment ceci :
CUSTOMISE CONFIGURATION FOR EACH FOLDER (CONFIG.PHP)
In Responsive FileManager you can customise the config.php for each folder.
Simply create a config.php file inside your desired folder, and set the config array only with the element do you need to change. (Don't change current_path,upload_dir,base_url,root).
You can also include an HTML text in the display folder page by simply inserting : 'folder_message'=>"html message" inside the config.php file in the folder.
You can use this to specify restrictions or images resizing.
Remember that the configuration of one folder is reflected in all its subdirectories.
et aussi ceci
Images configuration :
image_max_width, image_max_height / 800 / these parameters set maximum pixel width and/or maximum pixel height for all images. if you set a maximum width or height, oversized images are converted to those limits. Images smaller than the limit(s) are unaffected. if you don't need a limit set both to 0.
image_resizing / false / activate or not Automatic resizing. if you set image_resizing to true the script converts all uploaded images exactly to image_resizing_width x image_resizing_height dimension.
image_resizing_width, image_resizing_height / 800 / these parameters set the dimensions of the resized image. if you set width or height to 0 the script automatically calculates the other dimension. NB Very large images may cause the script to fail unless the server's php memory and time limit configuration is modified.
