Hi,
It is pretty easy to achieve what you are asking.
Please open this file:
ROOT/templates/
<yourjoomlatemplatefolder>/html/com_virtuemart/productdetails/default_images.php
And look for this IMG TAG (it is in 26th line):
<img src="<?php echo $this->product->images[0]->file_url_thumb;?>" alt="<?php echo $this->product->product_name ?>" class="product-image" />
Change it with this:
<img src="<?php echo $this->product->images[0]->file_url;?>" alt="<?php echo $this->product->product_name ?>" class="product-image" />
Also look for this TAG (it is in 35th line):
<a href="<?php echo $this->product->images[$ImageId]->file_url;?>" class="flexible-zoom-gallery" rel="useZoom: 'zoom1', smallImage: '<?php echo JURI::root(); ?><?php echo $this->product->images[$ImageId]->file_url_thumb;?>'"><img src="<?php echo $this->product->images[$ImageId]->file_url_thumb;?>" class="zoom-tiny-image-additional" style="height:50px; width:auto;" /></a>
change it with this:
<a href="<?php echo $this->product->images[$ImageId]->file_url;?>" class="flexible-zoom-gallery" rel="useZoom: 'zoom1', smallImage: '<?php echo JURI::root(); ?><?php echo $this->product->images[$ImageId]->file_url;?>'"><img src="<?php echo $this->product->images[$ImageId]->file_url_thumb;?>" class="zoom-tiny-image-additional" style="height:50px; width:auto;" /></a>
Cheers.
