Tiff images preview in the backoffice
Hey, it seems that tiff images are not previewed correctly in the backoffice. When looking at the rendered code I can see that images are displayed as follows:
```
<img class="umb-media-grid__item-image ng-scope" width="145.08489722966937" height="200" ng-if="item.thumbnail" ng-src="/media/1166/idealbar_-junckers__mg_4502.tif?width=500&amp;mode=max&amp;animationprocessmode=first" alt="idealbar_ junckers__MG_4502.tif" draggable="false" src="/media/1166/idealbar_-junckers__mg_4502.tif?width=500&amp;mode=max&amp;animationprocessmode=first">
```
It does not seem to set the format for non-web-friendly images to jpg or sth like that. Is there something that can be done?

Hey Vaidas,
Hae you tried adding the mime type to web.config? I doubt IIS would know how to handle it.
```
  <system.webServer>
    <staticContent>
    ...
      <remove fileExtension=".tif" />
      <mimeMap fileExtension=".tif" mimeType="image/tiff" />
    ...
    </staticContent>
  <system.webServer>
```
This might not solve it though as the browser may not be able to process a TIFF file as an image.

Thanks,
Jamie

Hey Jamie,

Thanks for the reply. I have the mime type specified since the images are used in the frontend.

I am rendering tiff's using format option
```
 var format = Model.Content.GetPropertyValue<string>("umbracoExtension") != "png" ? "&format=jpg" : "";
...
@Model.Content.GetCropUrl(width:Model.DefaultWidth, height:Model.DefaultHeight, furtherOptions:format)
```
So it's only the backoffice that has the issue.
