I've created size swatches for products in Magento 126.96.36.199. Is it possible to disable images swapping for selection of size options. I don't have images for my simple products so after click on size swatch Magento display blank images. I just want to have images from my configurable products to which my simple products are associated.
if you are using ce-188.8.131.52 ee-1.14.1. or higher, the feature is already built in, with the so-called Configurable Swatches which allow "Product Image Swap".
You can enable this feature in System > Configuration > CATALOG > Configurable Swatches

Here is an example of a configurable product image gallery images that contains images for three colors:
Swap Images Defined by Base Image
Another way to configure swap images is to upload base images to each child product of the configurable product.
Here is an example of a Royal Blue child product with an attached base image:
