Image dimensions is not the same as image size. The limit is based on the image size; though I am not sure what it is. - Edit:

To clarify, image dimensions are the number of pixels, say 300x100 for a total of 30,000 pixels. The image size is related to how much storage space the image requires. This number typically decreases if the image is compressed. For image formats without a fixed-size meta data portion, the image size increases with more mete data (additional information such as author, description, and date).
