I try to find some info’s here but all info’s was given in the wiki and book not working for me.
For testing I put the graphic inside the jar file but I guess there is an easier way.
If I put the graphic inside the better questing Folder in resources Folder how the path have to look like in the config file?

Thanks in advance.

Are you trying to replace the book image, or the image that loads when you open the quest GUI?

When I open the Book(Quest Gui). The title Page.

If you go into config/betterquesting.cfg and edit this line:

# Texture used in the quest tile card [default: betterquesting:textures/gui/default_title.png]
S:"Title Texture"=betterquesting:textures/gui/default_title.png

Change default_title.png to the name of your png file. Here is the source image so you can get the dimensions for yours.

https://github.com/Funwayguy/BetterQuesting/blob/master/src/main/resources/assets/betterquesting/textures/gui/default_title.png

Once you have the config updated and your image created, I would recommend getting the Resource Loader Mod (http://minecraft.curseforge.com/projects/resource-loader). Then in the root directory create resources/betterquesting/textures/gui and place your image in there. It should get picked up in game.

Looks like @Funwayguy has an easier way to do it:

https://github.com/Funwayguy/BetterQuesting/wiki/Resources

You just put the image in config/betterquesting/resources/< pack name>/textures/gui and in the config type in < pack name>:textures/gui/< image name>.png

I try it and get this. What i do wrong ?

I was able to reproduce what you are seeing.
In the config change your "Title Texture" to this:

gtnh:textures/gui/gtnh_title.png

In the config folder change all GTNH to gtnh. For some reason Better Questing is getting the information as all lower case which doesn't exist.

Ah ok thanks will try this.

Will change the packname name to "gtnh" and test it again.

Ok works with "gtnh". I let it open so long time it is fixed ok ?

If you look at Funwayguy/BetterQuesting#27 you'll see a note from @Funwayguy saying it's bad practice to use anything but lower case for resources. He's looking at implementing it, but I think it would be better to follow the standards and keep it all lower case.

Sure but more people will run into it and so i think its better it is supported.

@Funwayguy has updated the Wiki to warn about using all lowercase for the image path and config which closes out Funwayguy/BetterQuesting#27 and this issue.
