The "gallery" theme that uses thematic framework shows post as a thumbnails, 7 per row and 125x125 size. See the image here: [url removed, login to view]
However many websites have modified it to increase the size of the thumbs, like this one: [url removed, login to view]
I also want to increase the size of the thumbs and limit 3 posts per row. I believe it involves small modification in CSS file.
Please bid only if you are an expert and can really do this little modification for me.
