I don't know if this is allowed, and if it is, if it really belongs here. D': Thank you in advance. ❤️
If you're using Firefox, you can right-click on the picture and select "View background image...". It will show you the picture and its URL, and you can find out the name from it.
but sometimes the items have different urls that isn't really the name. :c
I know, but it gives you at least a part of the name. Then you can use subetahq or the shop search to find it :)
