I noticed that the gallery widget is using Medium images. Is it possible to force small for the widget?

Any ideas? Thanks

Yes, if the image has the medium image, it uses it:

		{{if $image->medium_file_name}}
			<a href='{$image->url()}' title='{lang="view_this_image" sprintf="$image->caption"}' class='ipsThumb ipsThumb_bg ipsThumb_large' style='background-image: url("{file="$image->medium_file_name" extension="gallery_Images"}");'>
				<img src='{file="$image->medium_file_name" extension="gallery_Images"}' alt=''>
			</a>
		{{else}}
			<a href='{$image->url()}' title='{lang="view_this_image" sprintf="$image->caption"}' class='ipsNoThumb ipsNoThumb_video ipsThumb_bg ipsThumb_large'></a>
		{{endif}}

Template Gallery -> Front -> Widgets -> imageRow.

Thanks! I changed them to $image->small_file_name and that works.
