    Gifs with transparent background turned black after upgrading to 7.5

    Currently using 7.2 and testing 7.5. We have some images that are gifs and have transparent areas. The images are resized with query parameters like "?width=100&height=100". In 7.2, this behaves normally and the image is fine. In 7.5, the transparent section becomes black (only when the image is resized as mentioned though).

    I'm not sure why this is only happening in 7.5 and I can't find anything saying this is an actual issue in 7.5. Has anyone else encountered this?

    We had this happen as well, I think it's because of an update to image processor between 7.2 and 7.5.

    The quickest fix is to add the querystring


    but if there are too many images then you can apparently you can add an extension method although I didn't need to myself.
