Having a variable in filename

[mo hab]

Does anyone know how to include a variable, in this case a counter, into the name of the files to be uploaded to a site? Please see attached file.

Example.
upload zennoposter0.png
counter +1
upload zennoposter1.png
counter +1
upload zennoposter2.png
etc.

Thank you in advanced.

C:\folder\string{-Variable.random-}.PNG

where random is random number.

First time it didn't work, because those files did not exist in my folder.
