Hi, I wish to create slideshow on an app but I don't want to update the whole app if I want to replace images. How can I achieve that?
There are many different ways this can be done, and what you do will depend on exactly how you want to do it.
Here is an example of a simple swiping slideshow, using a canvas, and a list of image urls stored on firebase:

Thankyou.
I wish to get image urls as user input and put those images in slide show. Users can replace the images at any time.
Do I have to use clock to make the slideshow automatic?
Facing error 'Cannot find the component textBox1' . How can we solve this?
Can you provide the .aia file of this?
What mistake i am doing? Why i am facing the error of 'Cannot find the component textbox1'?
I put all the urls in the settings of designer section of text boxes. And, i set the clock value to 1000 in designer settings.
here are the blocks.
Try the beta test version of the companion app
And click "Not Now" if you get an "outdated" warning
Also try to build the app and test using the apk file... does it work then?

I installed and tried opeing the app. Something is working even though the expected result is not happening.
The error message is changing like a slide show. ie, for each second the error message 'Attempt to get item number 1' is changing to 'Attempt to get item number 2' and then 'Attempt to get item number 3' and so on. How can i solve this error?
And, in AI companion i am facing the error 'Cannot find the componenet textbox1'.
Help me to solve this?
Read and understand your error message
You have a one item list
And if you get an error, usually you debug
Use the companion app and Do it to debug your blocks, see also tip 4 here App Inventor: How to Learn | Pura Vida Apps

Hi, I have 5 text boxes and i set each urls for each text box in a designer section. So, as a newbie, I think each text box data is each item in a list. So, there are 5 items/text-box data.
Which list has only one item in the above blocks? Can you please guide me to spot that mistake?
While using Do it feature, i am facing error 'Cannot find the component Textbox1'.
I think, if i give images directly using image picker, then it may work. il try it. I shall check and share the result here. But, what i do want is not that, I want to allow users to set their own image urls for slideshow.
I am modifying the idea of @Patrick_F . from this post.
