I presume you wanted to upload some files.
If the files are under 256K you can go to the options tab when you reply and upload one there. You will need to post two replies to upload them both.
If the files are over 256K you will need to post them to another site, such as dropbox, and post a link here.
HDR might be a way to go too, (sadly and/or intentionally omitted from PhotoPaint?) This was done with NIK (Google)
