I wonder, is it possible to read without the card reader.

Thanks with best regards,


You can get an external card reading adapter that plugs into a
usb port. I have one called "TOPRAM.  I don't remember where I got it,
but there are probably a slew of them available,  At any rate, it works
great. I took some pictures of my dog with a Panasonic Lumix camera,
put the SD card from the camera into the TOPRAM adapter, and it
read perfectly in PCLOS.I opened the picture files in GIMP. (The
TOPRAM adapter says usb2.0, but it seems to be plenty fast enough
for this purpose.)

I don't know if it's necessary, but I clicked on the adapter/card combo
in Dolphin before doing anything else. I understand that this mounts
whatever you click on. It also lets you figure out what /dev it may be
called, or you can copy the files to a local pictures directory and then
address them from there. This is actually what I did, since I wanted to
save the pictures anyway. If one of them turns out to be a clunker,
you can always delete it.
