If the magazine its just JPG files then you could consider to make it a CBZ file.
A CBZ is a folder of ordered JPEG files zipped but with the zip archive extension changed from ZIP to CBZ (same goes with winrar to CBR)
Then you can read it as a CBZ (or CBR player): add it to Calibre or read with CDisplayEx

Note: In Calibre / Preferences / Behaviour / you can change the default reader for each type)
