FAQ - Frequently asked questions

General and Installation

Q: How to create a desktop shortcut?

Q: JPegger seems to create thousands of jpeggeri.dat files. What are these good for?

A: If you do not want smaller images to be scaled to fit then use option "Shrink large images in 'Fit Scale' only. You will find this option on tab "Startup" in "Preferences" from menu "File".

Stability Issues

Q: When I right click with the mouse on a thumbnail or in the file list a context menu is supposed to pop up. But instead Vallen JPegger closes or even crashes. If I right click in the Folder Tree or the image or in full screen mode then there is a context menu.

A: This problem has been reported on some very view machines. This is not directly a problem of JPegger but with the Windows System itself, which is somehow corrupt. If you right click on the thumbnails then the original Windows Explorer context menu is called. This context menu contains all shell extensions that might be installed by any program on the system. When JPegger is calling this context menu some exception is caused by the Windows operating system which makes JPegger to close. The reason for this is that a previously installed program has not been uninstalled properly. Currently there is no solution for this problem. If you have also have this problem, please report for further investigation.

Hint: There is a workaround for this problem. In the Preferences dialog you can disable the Windows Explorer context menu and use an internal context menu instead.

The image selected is not supported by Vallen JPegger. We are working on supporting more Images

Q: Some images are not shown. The thumbnail is empty with a red cross. What does this mean?

A: The image selected is not supported by Vallen JPegger. We are working on supporting more and more formats with future versions.

Twain Import

Q: Twain import (select source) says twain.dll not exist.

A: The twain driver is part of your hardware scanning device (scanner or digital camera) and must be included with your hardware device. Install the hardware device specific twain driver from the device manufacturers software.

Printing

Q: Printing takes very long? Why?

A: Images need a huge amount of memory for pre-processing prior to sending the data to the printer. Depending on the available memory the printing process can take some time. All you can do is using smaller images or install more memory into your system if you want to increase the speed.

Q: I get an "Out of system resources" message during print and/or images on the page are blank.

A: Printing high resolution images takes a lot of system memory and you are running out of memory. Especially on Windows 9x machines you should be careful now as your system is getting unstable and it is recommended to reboot. This might result that you have several print requests in your printer spooler and you call the print command faster than your printer is printing.

Q: How can I change the size of the printed thumbnails?

A: You can define the size of the thumbnails for printing on Tab Thumbnails in Preferences out of menu File.

Sound Playback

Q: When trying to play a sound file I get the message  "MMSYSTEM257 Invalid MCI device ID.  Use the ID returned when opening the MCI device."

A: There is no valid sound codec installed. Vallen JPegger doesn't come with a built-in MP3 codec. It simply uses the standard Microsoft sound interface. If your sound plays with Microsofts Media Play it also should play with Vallen JPegger. Vallen JPegger doesnÆt use Winamp codecs. So if your sounds play with Winamp but not with JPegger then still the Microsoft codecs are missing or overwritten by another non-compatible MP3 application. Update your Media Player. If you have also have this problem, please report for further investigation.
