I use jetpack's "Top posts & pages" widget and I use the option "Image list" which displays a small thumbnail and a clickable title for each post.
Is there a way to put a custom size for these thumbnails? How can it be achieved? For instance, can I make these thumbs in size 100x100 px instead of the present size 40x40 px.
I wouldn't like to use the option "Image grid" because I need the titles of the posts as well.
