I found this article referenced on a LinkedIn Group and thought I would share it with the guild.
When developing your web applications, rather than having the item extension be ashx, if you make a simple web.config change you can keep the actual extension.
Check out the article on how to Remove the ashx extension in urls for media items in Sitecore and use the real type extension for the media items IE jpg, gif, etc
If you have any tips, tricks or resources you would like shared with the guild please email them to sitecoreguild@outlook.com
