Loading Screen / Recipes

Level 14
Oct 27, 2007
Hey, I'm a huge noob with map making and I'm making a map for my clan.
I'm doing quite well with it, except for two things:
1.) For the loading screen picture is there any specific format for it? such as .jpg or .gif?


2.) When trying to make like 3 items turn into one (such as the DotA item recipes or Custom Hero Line Wars recipes), whatever I try to do, it does not work.

Any feedback is useful, I'm sure it'll be something that's really quite easy that I just haven't thought of.
