That is correct but you also need to check that the SD Card Shield does not drive the SPI MISO pin due to level shifter (such as resistors). The same goes for the LCD. It is possible; here is an example sketch, CosaCanvasBMP that loads a BMP file from SD and displays it on a ST7735.

create code fences with backticks ` or tildes ~

like so
```
add language identifier to highlight code
```python
def function(foo):
print(foo)
```
put returns between paragraphs
for linebreak add 2 spaces at end
_italic_ or **bold**
indent code by 4 spaces
backtick escapes `like _so_`
quote by placing > at start of line
