Could not generate a possible card layout - error message without useful content

[francwalter]

Hallo
I tried the 57 cards set creation with images not of same width and height and then I got soon after starting createn this error message:

Could not generate a possible card layout

This is thrown in src/api/lib.ts in line 195 in function arrangeSymbolsOnCard when (symbols.length !== n + 1)

It took me a while to find that reason, with different widths and heigths the symbols can not be arranged properly.
So a first check of width and height and then an error message like:

Please use images of same width and height

could be very helpful.
Or at least some info about this in the README.MD

Thanks. frank
