Important notes:
- Only lower case options are supported (don't type any UPPERCASE letters for options) !
- Use "" for file names/paths with spaces! (example: "c:\images\dummy test file.jpg")
- Input file name (if required) is always the first parameter (unless /file or /filelist is used)
- Write always the FULL paths for file names (incl. drive letter)
  (hint for BAT files with relative paths: use the variable "%~dp0" to get the current path)
- You can combine several options in one command
- The commands will be processed in the order you write them
- Wildcards supported only for: /convert, /multitif, /multipdf, /panorama, /print, /info /jpg_rotate and /extract
- Do not set any other commands after /batchscan, /scan, /capture=5 or 6, they won't be processed
- Maximal command line length is limited to 4096 chars: use Drag&Drop, /file or /filelist for very large lists
- Most settings are loaded from the INI file. Using prepared INIs and /ini option, you can extend the possibilities.
- IrfanView exit code is 0. If /convert or /print is used, there is 1 or 2 also possible, for load/save error.
- Please test (e.g. conversions) first in GUI mode => some options may need to be set first (saved to INI file).


Example for conversion: 
  i_view32.exe c:\test.bmp /convert=c:\giftest.gif
  => Convert file: 'c:\test.bmp' to 'c:\giftest.gif' without GUI ;-)
  i_view32.exe c:\*.jpg /convert=d:\temp\*.gif
  i_view32.exe c:\*.jpg /resize=(500,300) /aspectratio /resample /convert=d:\temp\*.png
  i_view32.exe c:\*.jpg /resize_long=300 /aspectratio /resample /convert=d:\temp\outimage_###.jpg

  (Note: supported are all IrfanView read/save formats except audio/video)

Example for slideshow: 
  i_view32.exe /slideshow=c:\mypics.txt
  (Note: The file 'c:\mypics.txt' contains, in each line, a name of an image file, including the full path OR path relative to "i_view32.exe")
  (Lines starting with ";" will be ignored and can be used as comment)
  i_view32.exe /slideshow=c:\mypics.txt /reloadonloop
  i_view32.exe /slideshow=c:\images\
  i_view32.exe /slideshow=c:\images\ /reloadonloop

  i_view32.exe /slideshow="c:\images\" /filepattern="*.jpg;*.gif;*.png" /reloadonloop
  Note: you have to close IrfanView after the last image from the TXT file, if no /closeslideshow is used.

  => display thumbnails from directory 'c:\test'
  i_view32.exe /filelist=c:\mypics.txt /thumbs
  => load filenames from TXT file and display as thumbnails

Example for file: (this option is nice if you need to send the input file(s) as last parameter)
  i_view32.exe /file=c:\image.jpg (same as "i_view32.exe c:\image.jpg")
  i_view32.exe /convert="c:\result\*.tif" /file=c:\image1.jpg
  i_view32.exe /convert="c:\result\*.tif" /file=c:\image1.jpg "c:\spacy image2.jpg" c:\image3.jpg
  i_view32.exe /thumbs /file=c:\image1.jpg "c:\spacy image2.jpg" c:\image3.jpg
  Hint: you can create a special IrfanView desktop (or "Send to") shortcut which can use the files from Drag&Drop with other options like: "i_view32.exe [options] /file="
