Ok so I see alot of custom pictures on event threads and business listing threads, what do you use to edit the pictures? Here is an example of one I saw: https://empireminecraft.com/threads/shop-empire-flower-shop.75277/
Depends, but I could easily imagine that picture in the URL having been edited with The Gimp. It's a free open source image editor which is available for most platforms. Make a screenshot, edit it and you're done. Even an image viewer such as IrfanView can do do small edits (such as adding text and some image effects). (edit): Hmm, maybe I should do a tutorial on this sometime. It's been a while and questions like these have been asked multiple times before. I'll definitely add it to my toconsider list
I use paint.net (this is not the windows paint) to make my pictures, but I have to admitt that my pictures arent the most professional pictures around there . Some people have services for making pictrures for you too, so maybe that can help you if you aren't really experienced with photoshop?
A tutorial would be appreciated. I tend to use Paint.NET instead, as I just can't figure out GIMP well enough. I look things up sometime, but I'm not a person to read 30 minutes of text written by a stranger, just to be able to use a program. I can make text using GIMP, but with the cool effects used in that picture? I doubt I'd find a way.
AC Offers a service as well for these banners if you want one. They might still for a Picture for you if requested. https://empireminecraft.com/threads/closed-services-ac-graphics-architecture-promos-stores.48553/
