Hi iliil,

The main plugin field is CCK Field - Upload Jquery, and work with both

• Upload File
• Upload Image

  Images or Files are store on the server as it is set-up in those fields.  

Concerning the storage in database it's using the JSON storage, so you have to define the storage name like that:  column_name[field_name]

For exemple if you define imgs[plane], and have 2 image in your field, the storage in the column "imgs" will be like that:

{"plane":[{"aid":56821800,"name":"my-image.jpg","path":"images\/myfolder\/398\/","thumbs":"thumb1,thumb2,thumb3"},
{"aid":56821801,"name":"my-image-2.jpg","path":"images\/myfolder\/398\/","thumbs":"thumb1,thumb2,thumb3"}]}

This storage is true for all modes "Without Mapping" as "With Mapping".  

For the "Mapping" mode, you can generate a content in an other Content Type each time you add an Image or a File in this field. The link between the 2 Content Types is done with an extra Table to make the JOIN.  This mode is usefull as it allow you to display the collection with a SEBLOD Search.

For example, You can create a Image Gallery in a Content Type "Place". 

• Create the Content Type "Place"
• Create a Content Type "Gallery" with an Upload Image Field
• In the Content Type "Place" add an Upload Jquery field "My Gallery", set-up with the mode "With Mapping" on the Content Type "Gallery"
• ...

With that, each time you will add an image in the Upload Jquery Field, an entry will be created for the Content Type Gallery.

So now you can create a SEBLOD Search Type to display each image, with the template you want (Slideshow, Table, ...).

The Table for the Join is name #__cck_store_join_FIELD_NAME with 3 columns:

• id: the ID of the main content (Place in this exemple)
• id2: ID of image for the other Content Type (Gallery in this ecemple)
• ordering: allow you to order your content mapped

So like you can see, the storage of the content mapped depend on the set-up of your second Content Type. In most of case it's more simple to use "Article" object.

Hope, it will help.

Regards.
