Ah ok...
It is possible using the 'Custom CSS' field of the templates parameters along with the 'Module Class Suffix' field of the modules parameters...
1. Upload your alternative hover images to ../modules/mod_j51imagelinkhover/img
2. Add a name of your choice to the 'Module Class Suffix' field of your modules parameters, eg.
arrow
3. Add the following to the 'Custom CSS' field of your templates parameters..
[code type=css].module_arrow .j51container a.info {
background: url("../img/arrow.png"
}[/code]
Where
arrow is the 'Module Class Suffix' used in your modules parameters and
arrow.png is the file name of your alternative image.
Let me know if this works correctly for you
