Yes there are file size limits. You will need to resize the file size (number of pixels) of your pictures. Here is a direct link to the instructions for resizing. I simply reset my camera to use less pixels so the output is an acceptable file size for uploading. The lower pixel setting is fine for sharing pictures on the web. You really only need the high pixel setting for printing out pictures or blowing them up large.
