Comment made at: Freddy 014 c2cSorry to hear you've had a problem reading DCM files. Please forgive me if I misunderstand your problem or misjudge your level of computer expertise.
Here is one good way to handle your problem:
(1) Get yourself a good file archiver and a PDF creator. I highly recommend
(A) 7-Zip, open source software which can handle almost any archived file:
http://www.7-zip.org/ (B) i2pdf, excellent free software that converts a set of image files to a PDF document:
https://freeshell.de/~luis/i2pdf/(2) Download "Freddy 14" (Freddy_014_Charlton_Nov_1958_36p_c2c.rar), which is compressed as a RAR file (less common than ZIP or other formats)
(3) Right-click on "Freddy 14" to decompress it and create a folder containing all of the JPG images (folder creation happens automatically)
(4) Drag and drop the images onto i2pdf
(5) Use Calibre or other appropriate software to view your PDF
Enjoy your comic!
