TFT text over image

I am a bit confused using my TFT LCD with the adafruit library.

I wanted to print text over an image, but the text always comes with a box behind which makes the image disappear. Also it is not possible to reload the image afterwords (requires the whole screen to be updated. Any way to avoid this?

Kind Regards

Maybe switch to ucglib (Google Code Archive - Long-term storage for Google Code Project Hosting.)?
