Dvipng

[Cornelia Lutat]

I use intensively dvipng to convert tex to png.
However I can not configure the Programm to make it keeping the original file 
Name.

For example : xyz.dvi is converted to xyz1.dvi 
How can I fix it to get xyz.png out of the conversion?

I tried the Option -o but it did not work.

Thanks For a response
