This code and the SDcard CFunction was written when loading an image from the SDcard was very slow (c15s for 800x480 I seem to remember).

Since then the SDcard code has been completely replaced in the MM+ and is quicker and more reliable than either of the old solutions so I would recommend using the in-built LOAD IMAGE code as per Grogster.

As to why the flash code doesn't work - you have soldered a flash chip onto the display? and it is one of the supported ones? and it is big enough? The display doesn't come with one fitted

The reason I want to get Matherp's Pictures on serial flash is my main picture is a full size picture that takes a LONG time to load when it's a .bmp and so would the weather update pictures
I'd like to get this working as it would reduce the loading time and get rid of the need for an sd card.

Matherp if your around could you upload a copy of the leopard picture you used for this to see if I can get it working?
Are there any limitations on what can be displayed or should any picture converted to ASCII.PPM work?

Yes its got a Winbond 25064fVSIG serial flash (64MB flash) soldered on by Peter

Are you running the latest version of the MM+ firmware? Load image is now much faster than it was

Yes I am running the latest MM version
I've just tried it and it is 0.5 secs faster than the normal .PPM file type I was previously using

Anyway one of the main reasons for wanting to get this working was to get rid of the SD card because it sticks out of the bottom of the board, and as I want to put the weather display in a case when its finished this will make it a lot bigger and uglier than it needs to be (I'd rather not have an sd card sticking out)
EDITED:
