Hi Gardeur,
The Save Images part of SigGen should look similar to this
notice that the "Saved images directory" is using %s% which is
telling it to use the installed path and then the sig folder on the
end.
You do not need to tell it the full path.
I did not create any extra folders/directories on the ones that
are already created in the download.
You have to also ensure the folder/directory that the images are
going to be saved into has full write permissions, which is 777 if
using CHMOD on a unix based system.
After it is installed you should have a directory structure like below.
Notice that the ava and sig folders have full read,write,execute
attributes as mentioned above.
As you can there is a folder called img which hold all the original
graphics. 2 other folders called ava and sig which hold the created
avatars and signatures. The other 2 folders are used by SigGen.
I hope that helps.
