TGA or JPEG ?

Hello All
I have made a skin pack and changed a few textures from tga to jpeg ... this saves a lot of space. The shader didn't have to be updated.
And the skins work perfectly.
Is there a rule for using tga when jpeg works too ?
Thank you
using psp(mac) and gimp(pc)

I think the shader has to be tga. The real textures can also be jpg.

Yeah true
A skin I downloaded had a tga shader and a jpeg texture. That's what made me check this out. I reduced the size of the skinpack from 25mb to 9mb by converting large tga files to smaller jpegs. Haven't noticed a loss in detail or quality.
That's why I was wondering if there was some sort of rule for using tgas instead of jpegs. I don't want to end up crashing the server or causing a conflict in any way.
Thank You for answering
Respectfully

tga's can handle alpha channels. used for transparant parts of textures.

If the tga carries an alpha channel - it will be lost in the jpeg.

i have seen skin shaders where the file type was changed to .jpg though i see no reason to go through that if the file type lists .tga and it still accepts .jpg .

If that means Photo Shop then on the image menu with a graphic loaded click mode and make sure it says rgb color and 8 bits per channel .
