Pictures - Where do you want them?

Using the "Attachments" box at the bottom of the page, I can't upload from my phone for some reason.
It may be my phone (old Galaxy S10) - I can go to the "camera" folder where the photo is at, but then nothing appears for me to choose from.

On the other forum (Verticalscope) I can select the "photo" icon (like up above on here) up above and choose to get the image from the web, or from my phone.
On HERE, it (image icon) only gives the option to import an image from the web.
