To upload more files from your local storage to use for your Lookfy gallery, you can use the upload function inside Lookfy.
But sometimes you cannot upload your file, how will you solve this problem?
It’s likely that the file size exceeds Shopify’s upload limit for the media field.
A workaround:
Go to Content -> Files in your Shopify admin area.
Upload the file there.
Go to Lookfy app and add it to your gallery.
And you are done!
