To be successful when uploading your pictures you need to check the following:

Picture format
Pictures can only be uploaded in JPG or PNG format.

File size
The maximum file size is 1MB.

To check the file size click on your picture file with the right mouse button and select 'Properties' from the list that appears.

This example shows a file size of 168.0KB. There are 1000KB in 1MB so this file is fine to upload. If your file is 7MB or over follow the 'Changing your Picture size to reduce your file size' guide below.

Picture size The minimum pixel size is 227 pixels wide or 284 pixels high. Check your picture to make sure your width and height are above these values.

Changing your Picture size to reduce your file size:
In your preferred picture editor open your picture and find where you can edit the image size (sometimes called image dimensions).

Set the pixel width or height to 227 pixels wide or 284 pixels high.

Save your file and re-check your file size.

If your file is still to large or you can not change the pixel size try experimenting with the other image size settings in your picture editor.
