Get Names and Images of items via Iteam ID

[Maik8]

Hey there,
Direct to the point:
I want to use Item IDs like "3090" and want to get the name and (if possible) icon for that item, without scraping the images from the wiki or going the muledump approach of creating a big spritesheet and an item-matrix for it.
Also I found items with ids like this: 2695#5375860940134201, what does the "long"-ID mean in these cases?

Ideally, I would simply use the resources files of the exalt client itself, if at all possible.
I am going to use C#, so any solution or hint that works there is quite appreciated.

Regards,

Maik8

@Maik8 Add me on IM. I have c# code written for that and I can share some of it.

The long ID is unique item id. It is used to prevent duping / add enchantments to items (when they get released)
