First, welcome to TER!  
.
While your suggestions sound like good ideas, there's a problem or two with #1 and #3. Even though TER displays images (Provider photos on their ads; funny or informational images on various discussion posts), TER does not HOST those images. That is, TER does not store the images on their computers. That would require A LOT of disk space for storage. LOTS of bits or bytes. Which costs lots of dinero.  
.
Those images that you see are hosted (stored) on external image hosting sites such as imgur.com, ibb.co, imagecoast.com, postimage.com. When someone makes a post with an image, they insert a link that is embedded in the post; TER sends the link to the website; the website sends the image back to TER to display on your device. Everything is pass-through and TER doesn't need disk space ($$$) to store anything. But it still uses TER computer resources on-the-fly.
.
Also, the Profile is NOT AN AD!! If Personal Sections (photos, descriptions) are added, then the Profile becomes an ad -- I mean "buzz." Using the Buzz Boards means that info is (mostly) current and up to date. Through neglect, boredom, or other reasons, the Profile "buzz" becomes unreliable and outdated.
.
TER could, maybe, allow a Provider to embed links on her Profile (just like in a post) that would "call" for the image to be downloaded from the image hosting site. TER still doesn't store anything (except the link). But it still uses TER computer resources. And maybe the pictures become outdated. "Photos are of her ... but from 15 years ago." And maybe the links go stale. (E.g., Provider changes the photos on the image hosting site -- deletes Photo2019.jpg and replaces it with Photo2025.jpg -- and now the TER profile has a dead link to Photo2019.jpg "file not found."  
.
#2 - plain text self-descriptions take up much less storage space and display resources. But that info can also go stale.
.
Personally, I don't mind clicking on a Provider's web site links in her Photo Only or Regional Buzz Board posts or on her Profile.
.
I'll suggest some modifications to your suggestions: do not AUTOLOAD the photos or videos but let the viewer click on "Provider's Photo Links" (maximum 3? like on P411?) and click on "Provider's Video Link" (1 link). (Just like the current Profile has "Ad website: link-1, link-2, link-3" add "Photos: link-1, link-2, link-3" "Video: link-1"
.
Because it does require additional resources, maybe TER can charge a fee for those wanting to use that as an EXTRA feature. Beta-testers get a discount!  
.
Not a bad suggestion. I see some pluses, some minuses ... I'm neutral.
