Hi Kevin,

Can you describe a little further the steps in your process to get this error? Can you send me the image you're trying to upload so that I can see if I'm able to replicate this error?

The dimensions of the first image are correct - 912x1140.

We'll get this figured out!
Paul

Hi Paul,

Thank you so much for your reply. I'm sorry for my bad description.

Here are my all steps for my operation.

I download the images from the Internet and I try many different images, but they don't work.

Hi Kevin,

It seems like the issue has something to do with how the images are encoded from the web. I was able to duplicate your error.

The way I fixed it was to open the image in Microsoft Paint (or similar), confirm the resolution is 912x1140 and resave the image as a .bmp file (didn't matter if it was 16 color, 256 color, or 24bit). After I did that, the Lightcrafter 4500 GUI was okay with the image.

Try that and let me know if it works.

Best,
Paul
