The error message is self-explanatory; if you use color images they must be 24-bit RGB format (if you have RGBA, with alpha, it will not work);

if you use Grayscale images, you need to make sure they are saved in 8-bit format.

Also, the maximum image size is about 2MB

Hi,

My image is 24bits RGB.

Here is another one, in truecolor instea of palette.

Same error.

I tried uploading your second image to the Target Manager ( mini_magick20131107-12232-3jlxbi.png)

and it works.

The previous (first) image does not work because the color spae is indexed, and not true RGB, but the second image has no issue;

could you try again ?

your right, it's working, i must have mix something in my numerous tests !

sorry for the silly question

No problem. Glad that it works for you too.
