Abstract
We present a full next-to-leading order code to calculate the photoproduction of prompt photons. The code is a general purpose program of "partonic event generator" type with large flexibility. We study the possibility to constrain the photon structure functions and comment on isolation issues. A comparison to the ZEUS data is also shown.
