Hi
the image folder is writable since i succeed to upload others file .
About file extension supported i don't find any documentation about the list of file ( image or not exe ? pdf ? ) that ican upload using one of the two panel . I don't know if the focntionnalities for import are the same using the top or bottom panel !

what is missing is a stop button download in the case something goes wrong !!! ( nothing at this time but not important )
here a video in french about import image in hikashop .

Hi

Does create a reply instead of re edit my post is the way to go ?
