Hi Ian,

It looks like you use Wordpress. Could it be that your media database needs
some finetuning? I did the same with my websites ( <https://weetjedat.nl> and
<https://www.cryptocoinskopen.com> ), but they are buolt with another CMS tool.
In settings of CMS tools you can normally do some configs of the string that
is used by uploading images.

Greetings, 
Remco
