Has anyone resolved the apparent problem with transparency in PNGs when using the responsive images setting in PhpThumbsUp? This problem was raised by a couple of posters several months ago when the responsive feature was added (
http://forums.modx.com/thread/?thread=85893&page=2) but I cannot find a solution.
The code I am using is:
<img src="[[phpthumbsup? &input=`assets/images/image_with_transparency.png`]]" alt="">
On my site the desktop version of the image comes up without a problem with the transparency, but on iPhone, the transparent background is solid white?
