How to check for image src value

I am using version 9.4.0, and have an xsl code below:
<xsl:value-of select="aspdnsf:LookupEntityImage(EntityID, $EntityName, 'medium', 0, $AltText)" disable-output-escaping="yes" />

Which will give me the syntax to display image like:
<img border="0" id="EntityPic33" name="litter-substrate-paper" class="actionelement" src="/App_Themes/skin_1/images/nopicture.gif" alt="Litter, Substrate, and Paper" />

Could any one please tell me how to check the image src so that I can skip displaying the image if the value of it is "nopicture.gif"?

Thank you for your time.

We do basically what you're after in one of the 'out of the box' XML packages - entity.gridwithprices.xml.config:


<xsl:variable name="EntityImageExists" select="not(contains($EntityImage, 'nopicture'))" />


You can use that to check if the entity has an image or not.  There's also an XSLT method called aspdnsf:InStr that checks to see if one string contains another.

Thanks for your answer Scott. I have tried your solution and here are what I get:

1. I am using version 9.4.0 and can't find the variable "EntityImageExists" anywhere in the entity.gridwithprices.xml.config package.

2. I copied  and pasted your xsl syntax to the entity.xml.config package to see if it run, I got an error msg saying "unable to process request".

3. The XSLT method called aspdnsf:InStr, can you give me an example how to use it to check image source.

Thank you for your time.
Thanks Scott, I finally figured out how to apply your answer to my challenge. 
It was a big help and I greatly appreciate your insight.
Below is the codes, just in case anyone runs into the same problem:

<xsl:variable name="testing" select="aspdnsf:LookupEntityImage(EntityID, $EntityName, 'medium', 0)" />
                  <xsl:variable name="EntityImageExists" select="not(contains($testing, 'nopicture'))" />
                  <xsl:if test="$EntityImageExists" >
                         image exist.......
                  <xsl:if test="not($EntityImageExists)" >
                         image not exist.......
