You can resize with most decent photo editing software. If you havent got any google free photo resizing software"  
      I have an Armada book of fun on sale on amazon if you need better material.  
      I use 
Its quite a handy little 'poor mans photoshop'  
      Check the suffix is .jpg and not .jpeg
it might also be a good idea to rename the file manually and try it again  
      Some phones save the files as a jpeg but the format can be odd, usually opening in any graphics programme (even paint) and resaving will sort this out.
