Users importing images via FileMaker 11 from a folder so that they are viewable on their website (hosted using PHP API). All of a sudden they notice thumbnail backgrounds are showing up black. The images they uploaded are pngs, but FileMaker creates these jpg thumbnails out of those images. Why?
It should only resize the to thumbnail size, keeping the same format. Same thing happens in FILEMAKER 12!
It's not documented anywhere. Was this supposed to be an easter egg?
When I looked your container backbround was set to a grey checkerboard. If you select the container and set the background to clear, this might solve your problem. The image doesn't have the color, just the container object's background.
