hi i downloaded a skin, put it in my skins folder in lfs and it saved as a jpeg image and not a dds and then when i go on to new colours after restarting the game it isnt there plz help

Firstly, use punctuation.

It should be in LFS/Data/skins as a JPEG image. In order for it to work in game it should have the 3 letter car prefix in front of it, followed by an underscore. For example:

XFG_Skin
FXO_Skin

ok, thanks!

it still doesnt work!
It just won't appear on the new colours men. all the dates there are the 8/6/07. how can i update that list?

Have you clicked 'New colours'?

yes
