There are 13 files that are included in images under the `.tex`, but this is a typical error message I get for the first one, which is the same error for all with different file names of course, all of them are a `.jpg` file and worked earlier,

```````LaTeX Error: File `uob' not found.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
...

l.40 ...graphics[width=0.4\textwidth, center]{uob}

I could not locate the file with any of these extensions:
.eps,.ps,.eps.gz,.ps.gz,.eps.Z,.mps
Try typing  <return>  to proceed.`
If that doesn't work, type  X <return>  to quit.
