This should be not resize instead of not resize[0]

| return (images,) | ||

It would be advisable to use try-catch in this section to output appropriate error messages in case of exceptions.

When operating on a large batch size (eg 500) if the images are all the same size (eg a video), then the node ImageListToImageBatch takes much longer than necessary...
So this PR adds the option to skip the resize check and simply combine all of the images at once, which can be much faster from my testing (10 seconds vs 108 seconds with batch size 550, 512x512 res, tested on Colab T4).
