I ran in the problem where svg images were not loading using WorkLight preview. I found the solution for that here: How can I configure Worklight to serve *.svg files with contentType=image/xml+svg?
After adding these lines
<mimeTypes>
<type>svg=image/svg+xml</type>
</mimeTypes>
svg files appeared on preview, but now i can't load png files. Is there a way to make all the formats work?
Did you try to add another
type
for .png then?
