    Hi.
    Uploading PNG image with transparency is broken, i can upload image but processed images are broken, no matter with GD or Imagick extensions.
    For some reason they are “converted” to JPEG, but that JPEG cannot be loaded due to invalid marker

    cmp command shows 1 char difference
    differ: char 1, line 1
    first 4 bytes of original PNG
    89 50 4E 47
    processed:
    FF D8 4E 47

    image sizes that arent elegible for watermark are shown correctly and not broken, only those processed by image-watermark are broken

    updated, uploaded several transparent bg PNGs, including those which failed previously.
    Image uploaded, transparency is removed, image is correctly watermarked.

    I think there is no way to combine 2 transparent images using PHP Image toolkits?
