One of the noteworthy feature available now in Microsoft CRM 2011 is the ability to define ‘Web Resources’ which are a set of ‘virtual’ files that can be accessed from a URL (think: virtual folder holding the files on the CRM server).
One thing you can do now in CRM 2011 is store a couple of PNG files representing icons for custom entities, which is pretty cool since the PNG format is a lossless and well-compressed format which adds variable transparency compared to GIF which is a compressed format based on a proprietary patent!

So, from now on, please, SHOW-OFF your icons
