Searching for transparent PNG images, there are mostly logos and graphs, not real-life photos: https://www.google.com/search?as_st=y&tbm=isch&hl=en&as_q=&as_epq=&as_oq=the+OR+be+OR+to+OR+of&as_eq=&cr=&as_sitesearch=&safe=images&tbs=ic:trans,ift:png Maybe because it's easy to export transparent PNG logos from a vector editor, but drawing clean alpha channel for real-life photos takes time and effort. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
