<![CDATA[PNG and JPG formats: unsupported image type]]>Hi All,

I am really struggling with using imaged. It feels like it is a hit and miss every time. The UI edit shows the image, and when I upload the flow, I get an unsupported image type error. For example I wanted a background image, I tried JPG, PNG and none is accepted. Also used some PNG weather icons, and some are accepted, some are not.

I feel like it is impossible to tell which one will work and which will not. Maybe a validator in the UIFlow app would be useful.

I am using Paint.Net to convert me images. JPG export only has a Quality and a Chrome Subsampling option which I leave in 4:2:2.

PNG export a bit depth and a few other parameters which are used for downsampling the image.

Any recommendations are welcome.

Regards,
Csongor

Is that possible at all?
I guess it is not possible with either BMP and JPG.
