i use WYSIWYG Editor and add image in description product, upload multiple image ok, but i can't insert multiple image.
product have more image, insert one image very slow
how can i do ?
If you have WYSIWYG enabled for product description ( if not you can change it at the attribute properties Catalog->Attributes -> Manage Attributes) then when you click hide editor you will see Insert Image button.
Use this button to add any amount of images into description field.
