How do I make the images in default_roomtype.php bigger?

I've created an override for the default_roomtype.php in html/com_solidres/reservationasset/
The file I want to modify is default_roomtype.php.

I changed the grid in line 189 to <div class="<?php echo SR_UI_GRID_COL_6 ?>"> - - - was: COL_4
Likewise, in line 219 to <div class="<?php echo SR_UI_GRID_COL_6 ?>">
The grid works. The image remains the same in size.
The carousel controls are where they are supposed to be. Outside at the moment, as the image as it is too small.

I'm not a php programmer. I think the image must be sized somewhere between lines 189 and 219.
But I can find nothing to set the image size. The css doesn't give me a clue either.

Hi,

You can change the image size in Solidres Options - Media tab.

Then go to Solidres backend - System Info and Regenerate all thumbnails.
