It matters because each OS has a different paint program.   Not all jpg formats are created equal.  There is less variance than say avi files, but still many versions and options to the format specification.

Paste the photo into Paint (under Start all programs, accessories),  and then do save as, set the filetype to jpg and then type in the filename (without the extension, as it will add it automatically).  Try uploading that.  It's known to always create simple jpg files that are readable by this site.

 I think ioi said he might work on that.  He was surprised by how popular the option became and I think he didn't want to put too much effort into a feature that wouldn't be used.  Hopefully it will be something that we see in one of his future system updates.

i will try paint.

edit; nope paint gets me the same message......if someone could please add the picture for me i will be grateful...just that one game i am not going to add Megadrive games till i can add pics myself.

I fixed it for you TWRoO. Releasedate and boxart.

Ps: If there are games that you want to have a boxart just ask me (can send PM too).

 Cool, thanks for the reply. Now we only have to wait.

Thank you Konnichiwa

I ticked the unknown boxes for release dates load of time but it never seemed to work.... i assume you have to press save on the tab you were on for it to work wheras i ticked them, then clicked the boxart/page colour tab.

Just added all my GameCube games. There are a lot of boxarts missing though.

roller coaster tycoon for the pc anyone....??

Nice add man. Thanks.

I always get locked out of the board every time I try to add a bunch of games... it's annoying!
