I tried this but it is not working . For some reason I don't see my custom sign. The image is 280x140 and is in jpg format. I placed it on our clan server and when I browse to the image I see the image. I copied that URL and pasted it in the editor as described above. But I only see a standard sign. Even when I validate the track, saved it, upload it to our server and play the track online I don't see the image just a standard sign. The sign is not green so it looks like noting is saved in the track.To use your own signs you need an image. For large signs the size I usually use 280x140 to ensure an instant download, but some trackmakers go as big as 512x256 (It's always 2 : 1 ratio). Small resolutions don't look that bad in the game. Small signs should have 1/4 of those dimentions.
The image format should be .jpg (I think dds works too) for images and .bik for videos and animations.
If you want other people to see these signs, you need to host them at an internet location. I think freewebs allows file linking so it's ok for images, but I'd recommend your own reliable ftp server.
Once you uploaded them somewhere on the net, you just have to copy the URL of the file and paste it when using the "Paint pot" tool ("Select URL" option).
If a green sign appears, it can either mean that your file is being downloaded, or that it's too big (in size or resolution) or the URL just doesn't work.
When I open the track in WordPad I can see that the track is using a jpg image (something like Any\Advertisement\image.jpg at the top of the file). I also see (somewhere at the bottom) the URL to our server so it must be saved. Why is this not working? What am I doing wrong?
This problem occurs in TMS and TMN. We don't have a dedicated TMS server so that is not completely tested.
