Mosaic from database with GFLAx

[MihGer]

I want to create a mosaic picture from database stored images to show it on ASP page. Method Merge looks pretty suitable. But it can merge only files from file system while i have only BLOB's.

Of course it's possible to read pictures from database, shrink them, write to temporary files and then merge them together, but it's very ineffective way I suppose. Also I can see another very ineffective method of merging pictures with using GetColorAT/SetColorAT pixel by pixel.

Maybe someone can propose more effective solution?
