(disclaimer: 1st, I'm totally happy with the way DMT does TRs, but if anyone wants to be official...)
TRs should be (and generally are) a lot less complicated than mountain/rock pages. A TR-writer can be much more casual about directions (there really don't need to be any), maps, mileages, and route-finding.
If you use the bulk-uploader, and pre-edit the images to put in captions and titles in the IPTC data fields, the BU will do a lot of the work for you; there will be a list of the images, numbers and titles, which you can just paste into your text.
Free programs like Irfanview
(windows) allow you to embed the info directly in the jpeg, which can be quite useful if you later want to figure out why the heck you took that photo. These editors show the photo while you are adding the info, so you don't have to guess blindly.
In IrfanView, select image|information|IPTC button
...and edit the caption on the caption tab, and then select the origin tab and put the title in the "Object name" field. When the BU returns the list of figures with the numbers, it will put the title in the same line, in code that can simply be pasted into the appropriate place in the TR. The caption is the below-photo more-extensive text that we normally see when we click on photo objects. You can start each Title with "A." or "B." or "C." ... if you are worried that you won't be able to remember the order. Do this procedure for every photo you want to use in the TR, before you use BU.
Get the newest version of BU if you want to use this feature. Again, it's totally optional.
As far as I can tell, nobody polices to make sure you don't upload pictures of flowers and so forth. If they are relevant to the TR, have at it.
