I am trying to save a map obrtained from a map server via slippymap to a database. My code is below. My problem is that when I examine the data in the db (sqlite) I find a jpeg, not a bitmap. What am I doing wrong?

Thx.

ies = new TIESlippyMap(iesmpMapQuest, "c:\\mapcache");
TImEn2->IEBitmap->VirtualBitmapProvider = ies;
ies->Latitude = lat;
ies->Longitude = lon;
ies->Zoom = 12;
TImEn2->Update();

exif2->Edit();
picstrm = exif2->CreateBlobStream(exif2->FieldByName("map"), bmWrite);
TImEn2->IO->StreamHeaders = false;
TImEn2->IO->SaveToStreamBMP(picstrm);

SaveToStreamBMP does save a BMP, so the problem should be elsewhere.
How do you check the field contains a jpeg?
