I don't think that this is correct. If header[1] is 0 then it means that there is no picture at all, and not a picture without header (me thinks). When trying to start a program that uses the SSTab from TabCtl32.ocx without having assigned icons to the tabs it fails because wine tries to create icons that aren't in the stream. So there's no point in continuing and trying to read data from the stream. I could only make it work when I jump out of this function without doing anything if header[1] is 0. That may be wrong too but this patch doesn't solve it either.
In my case there are lots of *.bmp (with picture) with exactly same header i mentioned. Thus header[1]==0 doesnt imply 'there is no picture at all'
This pictures came in ole storage taken from a real win32 app, and loading them on windows works correctly.
Do you have VB6? Can you create a testprogram? If not then I can send you one. Just create an empty form and place the SSTab on it (the one from tab control, not the one in the standard palette). This fails on on my computer and I don't know how wine could detect if it's a headerless picture or no picture at all if they look the same (so far).
Thanks
bye Fabi

I don't have VB. In fact i ether dont have VC and windows installed at all here.
If you have an winelib based example, let's try get it working.

Maybe check header[0] to be real .bmp or .gif magic and header[1] for zero?
