In the traysection image, sks 7 save the .png images as .bmp...please correct this, i've edited the code editor manually for the .tga image

If a PNG is being converted to a BMP it will be because the image contains no per pixel alpha.

Why do you need it to save as a tga?

It was an image 100% transparent, because i've try an image .png and it worked correctly but then i want come back to original state without image so i've made an image 70 x 30 empty and when i've save it, appear .bmp with a classic black image, so i've edited the code editor manually and i've change the bmp with tga and all is return normal

Now i don't remember if this thing happens in sks 6 too, if yes is a suggestion for a future update

What I do for the tray when I don't want an image there, I just put a 1px color from the taskbar along the left edge of the transparent image I make, save it as a png, and then skin studio will convert it to a tga.  This happens in SKS 6...I found out how to work around it by trial and error.  As long as you have at least 1 px of a color, it will be converted to a tga by SKS.

It's a very good suggestion jazzymjr, it works on empty image too, but you must change the extension from bmp to tga in code editor

Been having some troubles with the "Parameters are Inconcorect" errors, just by choosing images from the dropdown list.

The section it's been happening in is the "XP specific section".

The whole thing stops working. The only way I can close it is the old "control, alt, delete" method and add it manually.

XP Home (SP3).

I highly recommend using the tip Jazzy mentioned. You can run across some weird things with totally transparent images.
