+* Added link_to_image(src, options = {}, html_options = {}, *parameters_for_method_reference). Documentation:
+
+    Creates a link tag to the image residing at the +src+ using an URL created by the set of +options+. See the valid options in
+    link:classes/ActionController/Base.html#M000021. It's also possible to pass a string instead of an options hash to
+    get a link tag that just points without consideration. The <tt>html_options</tt> works jointly for the image and ahref tag by
+    letting the following special values enter the options on the image and the rest goes to the ahref:
+    
+    ::alt: If no alt text is given, the file name part of the +src+ is used (capitalized and without the extension)
+    ::size: Supplied as "XxY", so "30x45" becomes width="30" and height="45"
+    ::align: Sets the alignment, no special features
+    
+    The +src+ can be supplied as a... 
+    * full path, like "/my_images/image.gif"
+    * file name, like "rss.gif", that gets expanded to "/images/rss.gif"
+    * file name without extension, like "logo", that gets expanded to "/images/logo.png"
+
 * Fixed to_input_field_tag so it no longer explicitly uses InstanceTag.value if value was specified in the options hash [evl]
 
 * Added the possibility of having validate be protected for assert_(in)valid_column #263 [Tobias Luetke]
