Just a wild guess here.
If you exit this procedure when extension is not jpg, jpeg or bmp,
then bitmap.free will not be called, so you have a memory leak???



JPGimage:=TjpegImage.Create;
try
JPGimage.Assign(bitmap);
JPGimage.CompressionQuality:=60;
JPGimage.SaveToFile(destinationFile); // <------- if ERROR, then it
will happen here
except
end;
JPGimage.free

finally
bitmap.free
end;
end;


I've never worked with threads, so if the problem lies there, I won't
be able to give any reasonable answers...
