how script create img catalog with images diferent dimesions?

I don’t think you understand the size of your task. You can’t get help in a forum, a few lines to copy/paste. It is a job for an experienced programmer.

It is for you to develop the algorithm. Plate optimization is a high end prepress task, and products command a high price.

1. Define your GENERAL rules. For example, will you allow images to be reordered? Will you allow them to be scaled? Will you take action to avoid white space, and what action?

2. Make the rules exact. For example, what is the maximum and minimum scale?

3. Work out your algorithm in all details. Be aware that in general this is the sort of tool that photo book publishers have invested years of programming and millions of dollars to create.

4. Implement the algorithm in code.

Do not be tempted to skip a step because it seems hard.
