A can't manage to use the plugin with "caos"

Hello, I’d like to turn a .jpg format in to a .dzi format. I’ve installed Deep Zeep Composer but I can’t understand if I have all the tecnological staff that are required. I’ve hade a look of a tutorial about Deep Zeep Composer and I’ve tried to “extract something”. At the end I got a fold in my pc with many files inside. Sorry but I can’t understand what I can do with these files. I mean, my aime is to be able to show my images in my Word Press blog, with Zoom Open Seadragon plugin. In fact I need to be able to show in details my old maps. Could you suggest me something to read about digital images in order to handle them and to be able to get what I want from them?!
Thank’s in advance

I assume that you have produced with Composer the following:
dzc_output.xml
dzc_output_files
- 0
- 1
etc. – folder with bunch of subfolders and jpeg files

if that’s the case, you are all set, just upload them (e.g. with ftp) somewhere to your site and point plugin to the files. Let’s say you are working with Via del Papa map. You can upload them, for example, to folder zoom/via-del-papa on https://www.fondofculturalheritage.it

and then your example shorcode would be
[gallery width="900" height="690" showrotationcontrol="true" caption="Via del Papa." openseadragon="true" noattachments="true" shownavigator="true" zoomimages="/zoom/via-del-papa/dzc_output.xml"]
