I am new in webnovel. I just want to ask how to upload a book cover in Inkstone? I really dont know how.
Uploading a Book Cover
Upload on inkstone on pc. Make sure the cover is 600 × 800 px jpg
On your Inkstone account, open up your book detail and press on the blank cover of your book to upload pictures. Warning, inkstone only accept 600x800 image only, slightly bigger than Wattpad.
This is what I do. (By phone since I have no laptop or PC)
Go to website, select desktop site on setting, Google your desired image, like this:
Princess in pink, 600x800
Most image you'll get will be in that size. Then you can edit it. But since Watpad cover app will make your pic smaller you have to use other app to edit your pic.
For me, I only use whatsapp. 
Fell free to check out my story, Love System: Changing Destinies and I'll check on yours too. Good luck.
