My product image thumbnails were not resized after migration. What should I do?

In case when Cart2Cart does not perform image resize automatically, pay attention that 3DCart has a peculiarity considering this issue. You need to use HTML code for setting the thumbnails to your product images: specify width and height in the HTML tag, e.g <img src="https://www.shopping-cart-migration.com/cart2cart.jpg" width="200" height="85" alt="Cart2Cart">

More information about the modification process you can find on 3DCart site.
