I can create a template page in atahualpa?
I want to create a page with fixed values​​.
for example.
name:
address:
etc.

Sure, use Index.php as a start and make sure to add the template comments at the begining of the file.

thanks juggledad, for replying, do you have an example for me?

My example would be the layout such as mail form CF7 looks like. a field for the name, address and message etc.

My goal is a form where people can enter their ad and upload a photo.

You need to do some research on creating a wordpress page template

I would just use Gravity Forms and put an upload field in the form.
