GetCropUrl() using cropAlias generates incorrectly sized image
In the process of migrating a v7 website to v8 I came a cross a very strange issue - This code:
```
<img src="@featuredPost.BlogPostThumbnail.GetCropUrl(cropAlias: "blogThumbnail", useCropDimensions: true)"/>
```
in a View, renders the correct ImageProcessor URL:
```
<img src="/media/4395/shutterstock_256320622_girl-with-tree.jpg?anchor=center&mode=crop&width=610&height=329&rnd=132276454024830000"/>
```
But the image as displayed, is shown as being 335 pixels in height, instead of the specified 329:

Has anyone seen this issue?

So, I've realized that ImageProcessor just isn't getting used at all - there is no "App_Data/cache" folder.

I have compared all the configs to the 8.6.1 download, and nothing seems amiss.

Hi Heather

Can you check files and folders permissions? Mayne Umbraco can't create a folder under /app_data?

Thanks,

Alex

Okay, so using this DOES work:
```
featuredPost.BlogPostThumbnail.GetCropUrl(610,329)
```
The generated img src is:
```
/media/4395/shutterstock_256320622_girl-with-tree.jpg?center=0.46832782948063639,0.58439388147611493&mode=crop&width=610&height=329&rnd=132339387248830000
```
but this doesn't:
```
featuredPost.BlogPostThumbnail.GetCropUrl("blogThumbnail")
```
The generated img src is:
```
/media/4395/shutterstock_256320622_girl-with-tree.jpg?crop=0,0.093333333333333338,0,0.097650273224043641&cropmode=percentage&width=610&height=329&rnd=132339387248830000
```
So perhaps those parameters aren't valid for ImageProcessor...

If I edit the url in the HTML via Dev console in the browser, and remove "&width=610&height=329" - the image displays properly.

So, perhaps this is a bug in the v8 implementation of .GetCropUrl(ALIAS)...?
