Nichole, Negronne vs VdB has been discussed in numerous old threads. Bottom line is that both have likely been sold under both names. They are quite similar and if you have either one (regardless of which name it has) you will have a good tree that provides good eating.
My Black Spanish may or may not be BT, but it is enough similar that I wouldn't go there if you don't want a BT. There are hundreds of better figs. Maybe BS has had different figs sold by that name, similar to VdB and Negronne. Yes, that pix looks about right (on the OGW site). It is a BT that has been nicely shined up.
Several years back a lot of us bought Danny's Delite, and it seems that there were to different figs in the 100 plants that were originally purchased.
Finally, if you went to http://www.ocnursery.com/#!fruit-trees/vstc1=fig up until a couple days ago, the Black Jack fig pix was of a Black Ischia from the Figs 4 Fun website. So, they were clearly on advertising correctly what they were selling. Don't know where the current pix came from but I assume that it is not theirs either.
That is the one advantage I have when I sell a tree: I have the parent tree (except in very, very rare cases), I know what the tree has actually produced, and I use my own cuttings (except in very, very rare cases). Doesn't mean I am perfect, but that I have very tight control over what I personally produce and sell. That is often potentially not the case with other operations.
