As you create pages, Pictavo will automatically warn you if the resolution of an image drops to an unacceptably low level. When this happens, you will be notified by the following popup message:
You will also see that the edge of the image’s box will turn red.
When this happens, it is best to reduce the size of the image so that it no longer gives the warning. However, if the image needs to be displayed at that size or you accept that the image may appear at an unacceptably low resolution, you can choose to ignore this warning.
