If you want to upload images and link to them from the source citations that's a nice (and often much appreciated) extra—but I wouldn't think of it as something to do instead of writing the best source citations that you can based on what you've got.
Suggesting that people just look at the document reminds me a bit of my 15-year-old self in high school geometry when I was asked to prove something was a triangle: "Um, just look at the picture?"
A good citation is a bit like showing your work in a geometry proof. The details demonstrate the reliability of your work.
For example, here's a good citation for a death certificate I got a copy of the old-fashioned way:
Certificate of Death for Lucius G. Heffron, 21 Jan 1913, Tacoma, Pierce, Washington, File no. 60, certified copy, author’s possession, Washington State Dept. of Health, Olympia, Washington.
Someone who wants to see a copy for themselves can use that information to search for an online copy or can send off for it as I did. They have all the information they need and know exactly what I was looking at.
On the other hand, here's a citation that I made in my very early days researching:
Last Will and Testament of Eli McDaniel, 1887 (probated), Orange County, North Carolina.
It doesn't tell me or anyone else where to find the record, such as the will book # and page or file box number, the exact date of it or where I might find a copy. Has the county retained the originals or films? Could someone write to them? Or are they at the North Carolina State Archive? Or maybe they've gone to a local or county genealogical or history society? Maybe it's a transcription or just an index I came across or someone told me it's there. I honestly don't remember. I now realize I know nothing about this source and don't trust it. You shouldn't either.
For now though, that's all I've got and that's how I would write the citation.
In your situation, I would suggest writing the most comprehensive citations you can for each document you have. Lots of the information will be in the document itself; some information you won't have. Like my examples, some will be good, some not so good. We do what we can and luckily no one is going to make you repeat a semester of high school geometry because of the not-so-good ones.
