New to reviewing tag edits so looking for some guidance. Noticed some edits inserting rather large images to tag info pages. The [google-chrome](http://superuser.com/tags/google-chrome/info) was not one I reviewed but an example of a really large image.

Questions are:

- Should edits with just a large image (assuming appropriate) be approved or rejected
- Any general guidelines on image size


My personal preference would be to use a smaller icon to not distract from the text but wanted others opinions.
