Thanks for reply!
I have tested in safari, firefox and chrome.
I tried to disable and enable resizing. I also tested to just disable the Image Limits and then enable it again, but nothing helped... Still just a grey background. Also tried to take away the picture (is it a grey background pic?) to have "no picture" and then upload again, but still no pic in the canvas area. I have also tried both jpg and png. No luck.
Can I have accidently done something with the settings some other place??
