Drupal 7.x

I want to prepopulate the user's dashboard with a small gallery of 3 pictures. I want the user to be able to remove them if they wish. So I am using Rules that triggered when the user completes the registration.

The Rules will create 3 nodes and prepopulate them with 3 images and some text. Text is easy. I cannot find a way to do it with images. I figured I will upload 3 images to the server and add an url to the field.

I'm getting a headache trying to solve a data problem about an exposed filter.
I must start by saying that this is a site that I started 3 years ago (I can't remember which version of Drupal 7) and then constantly updated in core and modules.

To start upgrading from Dupal 7 to Drupal 8 I installed the Drupal 8 Upgrade Evaluation Module.

I ran the module which generated the JSON file to upload to the golems website, I then transferred to the goelms website where I completed the requested details and uploaded the JSON file. When I clicked 'save' I was taken to a page with a progress bar.

It remained at zero percent for a period exceeding 18 hours!

I tried again and the same thing happened.

I'm working on two exposed filters that allow both multiple values.
They work, but I wanted to find out from you if the method is correct, since it seems a bit “twisted”.
To get the result I have to:
- Change the filter type from Single to Grouped
- Change the widget type to Radios
- Flag "Allow multiple selections"
- Save exposed field
- Reopen it
- Put the filter type back to Single

It works perfectly, but is this the correct method?

Many thanks or your opinion and suggestions

Would any know why my blocks would randomly shuffle? Sometimes one or two would shift up or down. Sometimes they would shift to a completely different region. There was one time every one of my block scrambled completely. Very odd behavior.
