progressive jpeg non correspondance

hello. Im back again because soem images i downloaded, work fine on my comp but when they are on moonshell on my r4, it says load error.
I held start and it says, blah blah

progressive jpeg non corresponance.
Can someone give me a clue as to why.
Some images i DL work. But its occasionally it doesnt.

 

Maybe the resolation is too high.Convert to something that fits the ds screen.
