Simutrans graphic packages are often developed by more than one person, so style differences are common.
Still, there are some guidelines that must be followed in order to see your work included into Simutrans; among these you'll find intersting to preserve the scale, lighting, colouring in the images you create.
To create graphics, every graphics programme can be used. To create a pak-file, the completed graphic data has to be converted into a png-file, if the graphics programme doesn't support this datatype. You can use many graphics viewer to convert these datas.
