Hey Danny!

I've actually been working on this same project and here is what I've found searching the web:

The Flickr api uses a variety of labels for this image sizes:

s - square 75x75
q large square
t - thumbnail
m -small
n - small
z - 640x 480
c -medium 800x600
b - large - 1024 x 768
o - original 2400x1800

So in line 16 of the code: photo['filename'] = "%(id)s_%(secret)s_z.jpg" % photo replace the z with another letter to change the download size.

Example: photo['filename'] = "%(id)s_%(secret)s_b.jpg" % photo

For some reason if you attempt to make the download option the original size, It will download a Flickr file not found

Here is where I got the info on the image sizes: https://www.flickr.com/services/api/flickr.photos.getSizes.html

So far the largest I've found that works would be "h" which gives a large resolution of 1600x1200

Thanks so much, that works perfectly!

My Pi isn't pulling in my photos from Flickr or booting into full screen mode

Would recommend opening the file as binary, which allows this to work on Windows-based box too. My tests were on a Windows Python installation which caused corrupt jpgs to be downloaded until I added the binary flag 'b'

Line 39:
image_file = open(path, 'wb')

Does anyone have an idea how to retrieve images from a personal photostream (and not just a Set or specific Album)?
The general feed allows you to use Ifttt.com to push new Instagram images to Flickr (https://ifttt.com/recipes/392-automatically-share-your-new-instagram-photos-to-flickr) which has a far easier implementation for photo frames implementations. The photo frame can then display most recent Instagram photos (Instagram seem to have closed their APIs for external app integrations)

Everytime I try to run these commands:

export DISPLAY=:0.0
XAUTHORITY=/home/pi/.Xauthority
feh -q -Z -F -z -Y -D 5 /home/pi/photoframe/flickr

I get the error below:
feh ERROR: CAn't open X display. It *is* running, yeah?

Any suggestions would be much appreciated!
