For some odd reason I don't remember how to upload gifs on DaniWeb.
Any help?
Gribouillis 1,391 Programming Explorer Team Colleague
In the editor, click on the paper clip, then browse your files. You may need to zip a folder with the gifs :)

Thanks a lot, here we go ...

Very nice, it works very well.

It is my understanding that you use Linux or the Apple OS X?

The linefor image in image_files)
is in your error code but not in the original snippet.
So, if you doctored up the snippet code, we would have to be mind readers to help you.

Can you tell me how to modify this to display jpg rather than gif pictures please?
Thanks

@micksulley This snippet https://www.daniweb.com/programming/software-development/code/467528/show-internet-image-with-tkinter shows how to open a jpeg image with PIL in order to display it with tkinter. I think it should work for you.

Many thanks, I will give that a try.

Sorry but I cannot get this to work for jpg. I assume that I need to change line 25, 30 but cannot figure out how to do it. I have tried many different things an none have worked.
I think my biggest problem is that I don't really understand those lines. I see what cycle does normally but in this case it seems to be returning two values tk.PhotoImage(file=image) and image, is that the case? I expected it to just return a file name, have I misunderstood what is happening?
Many thanks
Mick

You can add
from PIL import Image, ImageTk
import io
at the top, then add a method in class App:
def photo_image(self, jpg_filename):
with io.open(jpg_filename, 'rb') as ifh:
pil_image = Image.open(ifh)
return ImageTk.PhotoImage(pil_image)
Then at line 25, replace tk.PhotoImage(file=image) with self.photo_image(image).
Notice that this code keeps all the images in memory at the same time while running the slideshow.

Perfect!
Yes I guess memory may be the next problem, I will investigate.
Thanks for your help.

Hey! Cool script! I got a few questions though. First off, how do you make the script stop after the last picture in the picture list? Secondly, do you know how to make the pictures display at say half the resolution?
