| Subject: | The plugin does not support a size value bigger than 80 |
Quoted from the Gravatar developer documentation:
"You may request images anywhere from 1px up to 2048px...".
Currently any size value bigger than 80 causes the plugin to break.
Gravatar seems to work with sizes even bigger than 2048, probably returning that as the max size anyway, so I'm not sure if limiting the size in the plugin is really needed.
Without changing too much the code, it would be enough to change the size limit to 2048.
