How to create a book cover?
I cannot find a link where I can place my bookcover. The site only shows my latest chapters.. I've been searching for it for a couple of minutes now.. Please help me,
yukihirobi you need to go to the browser inkstone.com
There you need to explore the boom you want to add a cover on and press the gear in the upper right corner. It should bring you to the lance where you add the synopsis and title. Just click the cover and add it from wherever you’re saving it from.
for webnovel, the pixel size for cover is 600 x 800. use pixlr sites or befunky. they are good for photo editing and resizing. when you open pixlr or befunky, you will find photo resize option in crop/resize. add 600 for width and 800 for height.
Its better to not use other artist photos or photos with copyright coz you might not wanna get into legal problems in future. there are many sites like upsplash, pixabay...finding good photos there is a pain. You will find some photos and just mix them together in pixlr/editor. check sites for how to add layers or photo editing.
other option is google image search. in tools, go for option : image for non commercial use with modification. search for images with key words. you might want to try png format image because they are easier to edit. thats all I know about photo editing and book images. pixlr editor is also good for photo editing..then, there is photoshop and canva. online apps are without limits.

In need of covers, but don’t know how 
Jennifurr I am also a new writer on web novel. ANd I made my poster myself. You can use the websites or apps for posters or book covers. In start just keep it simple, or you can use royalty-free images if you need so that there won't be any copyright issue.
Or there are many good websites for making posters. You can look at mine, I made it like this.
