Adobe Fireworks CS5 does not directly support saving or converting images to the .dcr file format, which is typically associated with Shockwave files or Kodak's digital camera raw files. If you need to convert a JPEG to a .dcr file, you will need to use separate software specifically designed for that purpose. First, save your JPEG image from Adobe Fireworks by selecting "File" > "Save As" and choosing "JPEG" as the file format. Then, use a conversion tool or software to convert the JPEG to a .dcr file if necessary. To transfer the file to a memory card, you can use a card reader connected to your computer and copy the converted file directly onto the memory card.
