Converting Pictures:

Convert an picture using the HD Picture Viewer Converter: https://github.com/TheLastMillennial/HDPictureViewerConverter2/releases Refer to the HD Picture Viewer Converter's readme.md file for instructions on converting an picture.

Alternatively, you can use a web converter created and maintained by Peter Marheine: https://taricorp.gitlab.io/hdpictureconverter-rs/ Please note I cannot guarantee the web converter's compatibility with this program.

Written tutorial:

• Send "HDPICV.8xp" to the archive memory of your calculator.
• Send all converted picture files to the archive memory of your calculator.
• Refer to this troubleshooting video if you encounter any issues sending files to the calculator.
  • https://www.youtube.com/watch?v=-TweNnHuFCQ
• New OS version will require the HDPICV program to be run through the Artifice Jailbreak:

• Press Enter to open an image in full screen.
• Press Clear to exit.

Buttons:

Keymap in Main Menu: Clear ______ Quit program. Mode _______ Open help. Enter ______ Open picture fullscreen. Up _________ Select previous picture. Down _______ Select next picture.

FAQ

Is there a Mac or Linux converter?

The first-party converter is only designed for Windows. You can try using the alternative converter mentioned in the [Converting Pictures] section above.

How do I quit?

Press [clear]. If that's not working, press and hold the reset button on the back of the calculator for at least two seconds.

How many pictures can I put on the calculator?

This greatly depends on many factors: how many files you already have on the calculator, how large each picture is, and how well the pictures can be compressed. In an ideal situation, you could fit 833 pictures at native 320x240 resolution. I tested this by sending over 10,000 files to my calculator. It was physically unable to handle anymore files. A more realistic answer would be about 50 pictures total.

The picture won't show up!

This is because not all of the files actually sent to the calculator, or they were accidentally deleted. Try re-sending them. Press [2nd] then [+] then [2] and scroll down to AppVars. Verify all the files are on the calculator.
