Hi,

We encountered a "strange" problem with the image handler. It simply does not work for some reason. We get a 505 Internal Server error. I cannot see anything in the logs. 

Example:

https://mindflower.se/Admin/Public/GetImage.ashx?width=450&height=353&donotupscale=1&crop=5&Compression=90&image=/Files/Images/259823056_4617568454993382_7152987717000778027_n.jpg

Any ideas on this one? We have the same permissions as on other solutions. 

Regards / Aki

Hi Aki Ruuskanen,

i have had issues with GetImage handler when these DLL's are missing:



Not sure if it is the same issue but you could check if they are in the BIN folder.

As Jannich mentioned you might be missing some assemblies in the bin folder (ImageGlue7-32.dll, ImageGlue7-64.dll).
It sounds very similar to the issue reported here: https://doc.dynamicweb.com/forum/swift/swift/image-handler-returns-500-internal-server-error

Did you also create your application by installing Dynamicweb.Admin from nuget?

If missing assemblies is not the problem then it might be caused by a missing assembly binding redirect in web.config (which you probably copied from dynamicweb.web.config). You can try to add the following, if it is missing in web.config under configuration/runtime/assemblyBinding:

<dependentAssembly>
    <assemblyIdentity name="System.Drawing.Common" publicKeyToken="cc7b13ffcd2ddd51" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-4.0.0.2" newVersion="4.0.0.2" />
</dependentAssembly>

Otherwise you can try to take a look in the Windows Event Viewer and see if any logged event contains more details about the error.

Best regards,
Morten

Thanks Morten, it was the dependentAssembly section that was missing.

I'll find the responsible developer and give him ten lashes (unless it was me).   :)

This also happened to me, I installed using Nuget console, version 13.1.

Morten Bengtssons answer fixed it!

So maybe it's missing from the dynamicweb.config(?).. in that case everyone should have this problem.
