Screenshots??

Doesn't seem like it. Another thread, https://smilebasicsource.com/forum?ftid=1400 has largely discussed the implications of lost screenshot functionality, so it might be worth watching if conditions change.

So yeah... To take a screenshot on SB, press the Select button. For cases like the OSP Programming contest, You would take a screenshot on SB, Turn off your 3DS (Save your stuff first), take out the SD Card. If your using a Micro SD, you may want to use an adapter (Like me). Put the SD Card in your PC (If it has a SD Card slot), open the folder where your pictures are stored, (Your DCIM folder), Don't open the Android folder that may be in the DCIM folder. Open one of the folders and copy the pictures that are in the folder to your desktop, You may want to make a folder called "Nintendo 3DS Pictures" onto your desktop. After the Pictures are on your desktop, you are free to take the SD Card out of your PC and put it back in your 3DS. You are finished! (This also works for Android devices)

You can also upload the images using the 3ds browser

You might need to search for it. SD CARD ⇒ DCIM ⇒ Last folder with NIN ⇒ HNI_ (Last file) .JPG You cöüld upload it to the Kland buckets and get it there too but the graphic might become worse.
