Just a pic PSA really, though if Roon wants to see a copy of the original non-compliant pic(s), let me know & I’ll upload.
Did a little experimentation & found how to fix pics that were showing up in skipped files for no reason I could otherwise ID.
I had earlier tried renaming the pic and/or the folder name and/or relocating the pic, but that didn’t work.
I then took the pic into MS Office Pic Mgr (but I’m sure it could’ve been any basic pic editor) & re-sizing them downwards to varying degrees to see if I could find the max size allowed. All re-sized variants worked (did not show up in skipped files), and even 90% or 99% (of orig size) would take the alt pic out of the skipped files purgatory.
Then, as a last test, I resized to exactly the same size, and to a size exactly one pixel smaller in both the W & H dimensions. Those worked too.
See the 2 pics below as examples. There is a big difference in file-size, even when I re-sized (not compressed, by the way) to exactly the same dimensions, so I assume there was some weird header, or other aspect of the file that I know nothing about.
Anyway, if you’ve got a pic stuck in “skipped files” purgatory, try re-sizing to the same size, and see if the copy becomes Roon-compliant.
edit – sometimes that doesn’t work. But in that case, the one with 1 less pixel each dim worked. In another case, a straight copy worked. In another case, un-ticking the “Archive” attribute in Properties worked. In yet another case, converting from a .tif to a .jpg was required. In short, if you futz with it, you’ll probably be able to make them work.
So, for instance, in the pics below, for Dave Davies testing & DSC9093 show as skipped files, but DSC9093-copy 9 & copy 10 do not. And for the Chet Atkins, CDTray remains in skipped files, but the other 2 variants now work.
