I tried this:

search:
Fig._[0-9]+[0-9]+.[0-9]+[0-9]+

replace:
Fig._[0-9]+[0-9]+.[0-9]+[0-9]+<img src="../Images/Fig._[0-9]+[0-9]+.[0-9]+[0-9]+.jpg"/>

and I found correctly chars:

Fig._10.41

but it is translated into:

Fig._[0-9]+[0-9]+.[0-9]+[0-9]+<img src="../Images/Fig._[0-9]+[0-9]+.[0-9]+[0-9]+.jpg"/>

maybe some special char in replace makes the regular expression not executable?
Please, help!
