Forum:Vector images and ideal preview images for categories and the "Read More" section

I have two questions, all relating to the preview images for the top section of a category page, and the preview for the "Read More" section on the bottom of any page.


 * 1) How come vector images (SVG files) do not show up as preview images? Vectors show up in the "New photos" section and in galleries. I tend to do most of my work in vector, and it would be nice to seem them in previews.
 * 2) I believe that the first (non-vector image [see above]) to be placed in a page automatically becomes the preview image. But based on several page standers (at least on the wikis I use), the first image I post is not usually a good preview one. Is there a way I can make another picture within the same page the preview?

I appreciate any help I can get. Thank you in advance. --NuclearVacuum (Talk) 01:26, June 19, 2012 (UTC)
