[SOLVED] Request for Author page, H1 title in tag page and alt tag for category icon

I recently saw a couple of errors being reported by Bing webmaster tools and found some minor issues with the theme that if implemented can get my reports clean and user experience improved.

No H1 header tags on tag and category archives
There are no H1 header tags for tag and category archives by default. If added above the loop, they would not only give user the visual clue about the page but also get rid of this error.

I added one for my website on a tag page by customizing the file but i have to redo this on every theme update. http://www.funinfinite.com/tag/shayari/

Missing alt description on category icon in post footer
The other reported issue is for missing alt tags. This was narrowed down to the icon beside post category. I couldn't find a way to add alt description to it myself. Would appreciate if added as it would make the reports a lot cleaner.

Request for Author template
Thirdly I would really appreciate if an author page template may be added to the theme. My site is a fun content submission site(http://www.funinfinite.com) and users like to get their info showcased in a page. Currently if i add author.php, it shows just his posts and no bio. If, at minimum, a bio box is added to top of 'the loop' which shows author pic and name and a short description, it would do the job. Rest of customization may be left to the webmasters.
