I’m not sure what you’re asking, but [is FITSIO.jl what you’re looking for?](https://github.com/JuliaAstro/FITSIO.jl)

Thank for your feedback. I trying to generate a database. With the line that i shared I just can generate one image at each execution. I would like to give to the code a file and he generate for me a lot of image at once.

By “generate” you mean “read from file”, yes? And you have a FITS file containing many images which you want to read in at once? Then FITSIO is what you want.

Read the file in to a FITSIO object, then loop through the images in that object. I can’t really be more specific than that, because I haven’t heard of the format before today, but I think the documentation for that package should get you started.
