Needing a bit of help

[John4300]

This is a spriteset of Gradius 3 (SNES) walker. This is also my very first spriterip posting, I thought some people might actually need this.

So, I'm having two questions:

1) How to make those cool icons or preview pictures you see in TSR? The tutorial talked something about a maker, but I didn't find the downloads page...

2) Is this set ok? I think it should have everything from the boss, ripped with mostly using vSNES/ZSNES combo. Should I edit the tileset some or the texts or something before I post this? I know the font looks awful and common, but it's good for smaller sizes..

Thanks for your help
