Hi Dean, Sorry there was a small mistake in the code, try this:

<%# IfEmpty(Eval("BlogPostTeaser"), "", "<img class=\"classname\" src=\"" + GetFileUrl("BlogPostTeaser") + "\" />") %>

The GetImage() method is compiled and part of the Kentico DLLs. You might look into changing your method use and/or use a different field for the image where you can use a URL vs. having it create your full <img> tag for you.

Dear Deann,

I cannot give the orginal Kentico code for the GetImage method, but what do you need to do?

If you only want to add an css class to an image you can also do this in your transformation with standard Kentico:

<img class="CLassName" src="<%# GetFileUrl("NameColumnOfYourImage") %>" />

Another example with an news teaser image:

<%# IfEmpty(Eval("NewsTeaser"), "", "<img class="CLassName" alt=\"" + Eval("NewsTitle") + "\" src=\"" + GetFileUrl("NewsTeaser") + "?maxsidesize=100\" />

Good luck and if you want to do something else or more please let us known, probably we can help you further.

<%# Eval("BlogPostTitle", true) %>

Found the only solution is creating a custom transformation, which I can, just need to know what I am adding, so if I know what the current method looks like I could create it.

Hi Dean, so if you change your transformation to:

<%# IfEmpty(Eval("BlogPostTeaser"), "", "<img class=\"ClassName\" alt=\"\"" + Eval("BlogPostTitle") + "\" src=\"" + GetFileUrl("BlogPostTeaser") + "\" />") %>

Is this working for you?

Not quite.. This worked <%# IfEmpty(Eval("BlogPostTeaser"), "", "<img class=\"col-md-5 img-responsive pull-left\" src=\"" + GetFileUrl("BlogPostTeaser") + "\" />") %>

The alt part exported each word of the post title like="" This="" So I took it out for now. Many many thanks.

Hi Maarten

I noticed that when you remove the file extensions from the settings.. the image will not render. You'll get something like this:<img class="news__image" src="/getattachment/43955191-ffd4-435b-b60a-a47864cdfe1b/"> . This will result in a broken image, unless you add some text after the last / . Any idea what's wrong? I have a simular topic on this http://devnet.kentico.com/questions/kentico-9-getimage. But it's a strange thing which I'm having over and over again.
