I only checked it in the editor, and much cars seem to be invisible (only wheels and lights) some are white and some don't have wheels. I suppose these couls be misconfigurations. Do you mean convert an eft to jpg? That's impossible. The jpgs we got in the download center are converted by Sixteen Tons If you mean convert jpg to eft, this can't be done. You must convert the jpg to tga and then the tga can be imported to the editor and will be converted. Here are the required settings for the tga file: TGA 24 bit & NOT comprimed 512 x "X" on two sides meaning that you must have 256x256 , 256 x 512 or something other that can be ":" with 512 72 dpi Yes and no, this depends if you have a fully written readme of the mod with all original authors of vehicles, houses, scripts, childs,... and this depends if you really where allowed to use them
