Project image thumbnails

I have read through the support thread and it seems that we are unable to change the project image sizes on the front page. I do not have larger images of my projects? I just feel that the thumbnails look out of place on this full screen wide theme. Is there a way to make larger thumbnails without uploading larger images or manually add images?
