MAKING BAMS, problems about making original BAMS and green bottom visible IG Options

[Rigel]

Hello i'm working on a MOD for BGT-BG2 called "GOODS of FAERUN". It's a MOD who add some merchants, few little quests and a lot of new items. I will make a merchant who sell armors and helmets of diferent colours but with no special caracteristics, it's just a black helm, or a dark red plate for fun, just to be fashion; however...

I will also create new ITEMS, and in that purpose, i need to create new bams; i will recolorize existing bams with news colours schemes.
I make 2 bmp files with a selected bam and after i work on them under GIMP 2. Next i use ITEM GRAPHIC CONVERTER to get a "quite" new original bam.

It's quite easy to do but i've got a big problem: i see the green bottom of the bams IN GAME; i've made some ressearches and i think it's a ALPHA CANAL (who set transparency) problem. It's like some graphical zones were losing their transparency during the change betweeen bam file becoming 2 bmp files.

So if someone know something about that graphical problem, i would be so glad if you can help me, and explain me how it works exactly, and how dissmiss that green bottom, if you can indicate me a tutorial it would be nice too. I'm not afraid of complicated explanations: i want to know all about that subject, cause i need to be a pro item creator.

yeah, its possible you lose some pixels when you reduce the size of your pic (by linearity or other method) and your item can look bad if you don't watch in detail. They look better in game, with this fluo green it kill your eyes. These bams were just some tries, think too the shadows are not very placed. I'll post my nexts who will be best cause i'll make them for my mod.
