Hey Kyleran, sorry this question got skipped.
This is the announcement post which includes IP requirements for each of the things you are asking here.
- 250 Influence
- Also 250 Influence, unless the link goes to the CoE site or the Wiki,
- Images, I imagine would fall under the 250 rule as well since you are linking to another site.
Soooo, I guess just 250 influence for all of the above :P
