The files that I need to download are .jpg and all of them start with the
character "7".
For example: 7-waai.jpg, 7-ooqp.jpg, 7-ahok.jpg etc.

What is the best way to grab these files only?
The server contains other files - which I have excluded with the following:
-*.log -*.lst -*.txt -*.zip -*.ini -*.gif -*.html -*.htm -*.js -*.xml -*.png
-*.exe

I added the following to only include .jpg files starting with "7":
+7*.jpg

Using the above method, I get all .jpg files including the ones containing a
"7". 

Any ideas?
