Firstly you need to check the format that the pictures are in, the site will only allow certain formats.
To do this you right click on your picture and go to properties. Then when the properties launch under the general tab you will see “Type of File”, this must be one of the following.
jpg, gif, jpeg, png, bmp, mp3, mpeg, avi, mpa, mov, qt, swf
If it is one of these you then need to look at the size of each picture, each user has a 5MB allowance in total for their pictures. Each picture must be no larger than 2000 KB. This can be found again in the properties tab under size, if you picture is larger than this it won’t upload. You will need to resize any image over the limit which you can often do with any software that may come with a digital camera that you may have.
