Before I list the websites that hosts stereoscopic 3D images that's compatible with the Nintendo 3DS, allow me to post a summary on stereoscopic 3D images on the Nintendo 3DS:

• Stereoscopic 3D images are two offset images (one for your right eye, and another for your left eye) packed in an .mpo file. Normally you'd need a special stereoscopic 3D glasses to view that type of images, but the 3DS is able to project the two offset images simultaneously without the need for special glasses.

• You can view and download low resolution stereoscopic 3D images in the Nintendo 3DS' Internet Browser. The 3DS is unable to load high resolution stereoscopic 3D images in its Internet Browser due to RAM limitations. A "cannot load this image" error will show up if you attempt to load a high resolution stereoscopic 3D image.

• You can view your downloaded stereoscopic 3D images in the Nintendo 3DS Camera software (pre-installed on your 3DS).

• You can view all stereoscopic 3D images with the stereoscopic 3D mode off, but unlike stereoscopic 3D Nintendo 3DS games, you have no detailed control on the depth. In other words, the stereoscopic 3D mode can either be on or off, not in-between.
