Hi Javed,
Sorry for the delay in reply.
This is something we will look into adding in a future release.
I've had a look at the CMS Builder core files, and unfortunately there isn't an easy way to add more thumbnail images without heavily modifying the current code.
When I've come across this issue on a project, I use the closest larger thumbnail image size, and use CSS or HTML to resize it to the correct height, for example:
<?php foreach ($blogRecord['uploads'] as $upload): ?>
<img height="100" src="<?php echo $upload['thumbUrlPath']; ?>" alt="<?php echo $upload['info1']; ?>" />
<?php endforeach ?>
By setting just the height, the ratio of the image will be correct, and by shrinking a larger image the quality will be kept.
Thanks!
Greg
