In these cases, equal size of the target image is 'roped off' for each tile size, i.e. 210 x 280 tiles will cover the same amount of total space as 30 x 40 tiles. Thus, allowing more sizes will diminish the amount of space that the largest size will take up. This leads to more representative mosaics. However, since images can be reused in different sizes, allowing more sizes allows for more repeats.
In general, I think allowing more sizes is a definite win. There are still many intelligible, large images, but there are not too many 'gigantic' images that ruin the mosaic as a whole.

Here's a great example of a case where too many giant tiles (the boobies and the chickadee) ruin the mosaic. The mosaic is improved, and the collage is still interesting. |
