Importing different pictures formats into one document ?

Hello everybody,

I would like thanks to Automator to import different pictures formats into one document.
A picture says more than 1000 words and here it is : http://www.willemsens.net/test_formats.jpg

To do that, first of all I’ve done different folders, a folder for each format.
Thanks to Automator I’ve been able to “transform” each picture into the format I wanted.

Now, I need to make a 5 x 7 format at 300 DPI to import the pictures.
I’m not sure but InDesign could be the solution, but how to give a name to each picture box ?

In fact to make things easier, each picture has the same reference for example : picture 1 is picture1.jpg in every folders in colors or black and white or sepia ect.

This way I think if Automator could go into each folder and pickup each picture and it would be easier.

Any idea is welcome, in fact it’s for a school and I’ve 18 different classes.

Best regards,

Thierry
