magento 2 displays small picture in catalog

Question

My magento 2 was fine, I upload big image and the display was fine, now, new products show up small (the one in the right), see my screenshot :

I didnt edit my view.xml so I dont know how this suddenly occured!!! both image in the catalog page are the same size in fact, but obviously whn I uploaded the image, magento makes the pic small and a big frame around.

here is a part of my view.xml:

    <image id="category_page_grid" type="small_image"> <!--page categories product list height -->
        <!--<width>925</width>
        <height>1388</height>-->

I think this is not good solution to change in core files.so use https://bitbucket.org/fred_imgmedia/imageproccess.git extension for the same will work for you.

Magento\Framework\File\Uploader.php contain constants MAX_IMAGE_HEIGHT & MAX_IMAGE_WIDTH which is set to 1200 by default

or you can change in

magento/module-backend/view/adminhtml/templates/media/uploader.phtml same
