Contact sheet with single picture ?

[yetanotherlogin]

Hello,

For a new ID card, I need to…
1. Turn a 420x540 pixel picture I took into 3,5 hz x 4,5 vt cm
2. Use that single picture to create a 15 hz x 10cm vt cm contact sheet — so it'll have 4 columns and 2 rows to fit — before getting it printed.

I didn't find if IrfanView suports this. If not, what other free app would you recommend?

Also, does DPI matter when resizing the picture into 3,5x4,5cm, or it's just a matter of how fine-grainted I want it to be (in which, case, 300 DPI is better than the default 72 DPI)?

Thank you.

Edit: As a work-around, I ran the following DOS/cmd command to copy the picture several times, and saved the contact sheet as a picture with different DPIs. I'll see what the photo printing machine does with them.

for /l %A in (1,1,8) do copy ".\input.jpg" ".\output-%A.jpg"

Create a folder called Contacts in your Pictures directory. Put the following commands in a batch file (I use 4_pics.bat):

if %1. == . goto regular
echo %1 >"%USERPROFILE%\Pictures\Contacts\list.txt"
echo %1 >>"%USERPROFILE%\Pictures\Contacts\list.txt"
echo %1 >>"%USERPROFILE%\Pictures\Contacts\list.txt"
echo %1 >>"%USERPROFILE%\Pictures\Contacts\list.txt"
echo %1 >>"%USERPROFILE%\Pictures\Contacts\list.txt"
echo %1 >>"%USERPROFILE%\Pictures\Contacts\list.txt"
echo %1 >>"%USERPROFILE%\Pictures\Contacts\list.txt"
echo %1 >>"%USERPROFILE%\Pictures\Contacts\list.txt"
echo %1 >>"%USERPROFILE%\Pictures\Contacts\list.txt"
start "" "C:\Program Files (x86)\IrfanView\i_view32.exe" /thumbs /filelist="%USERPROFILE%\Pictures\Contacts\list.txt "
goto end
:regular
start "" "C:\Program Files (x86)\IrfanView\i_view32.exe"
:end

You may need to correct the "C:\Program Files (x86)\IrfanView\i_view32.exe" to the correct location if, for example you are using 64 bit IV. Drag your photo to the batch file and the thumbnail window willl open with 9 copies of you image displayed. Then make any contact sheet you want.

Create a shortcut to the batch file on the desktop (or anywhere else) if you use it a lot.

Not sure about the DPI.
