I understand that wikkii has passthru() disabled for security reasons, and therefore is unable to support .svg images. However, a member of my wiki was very determined to use .svg and found a wikkii wiki where an .svg was used without problem, so I looked into it more and found that they had imported that image from wikipedia. So, I tried to do so on my wiki, and was able to successfully import and use a .svg image from wikipedia on my wiki (iiwiki.wikkii.net). However, as usual, uploading them directely would result in the errors.
Is there a reason why this is the case? And if I am able to view and use .svg images imported from wikipedia, would there be a way to get them to be shown via the regular upload file method?
For reference, my wiki is: http://iiwiki.wikkii.net
and the image that I imported from wikipedia is here: http://iiwiki.wikkii.net/wiki/File:Flag_of_the_United_States.svg
However, other .svg's display errors as shown here: http://iiwiki.wikkii.net/wiki/File:Solmsayshi.svg
