XF 1.5 Remove query strings from avatar's urls


Active member
Hello, i created a small mod and use htaccess for removed a query strings from avatars.

for example:

before: data/avatars/s/0/1.jpg?1468399043

after: data/avatars/s/0/1468399043/1.jpg

I am not a professional programmer, and so my question is, what pitfalls or problems do I get if I use this method?

Thank you!
