2 questions about AVATARS (vB 4.2.1)
 

1)
Ok, first of all, I want to know why wouldn't be a good idea to render "external avatars" instead of storing them directly into my DB, so I get rid of that link "image.php?u=10912&dateline=1386613040"?
I know about the image's uptime, I don't worry about broken links of avatars' URL :D

I mean, if I want to show avatars like this:instead of this HOW TO DO THAT?

2)
I've installed a new template, and I need to modify the allowed size for avatars to a new smaller size.
I can't resize each user avatar, so I want to RESET them.
How can I reset all member's avatars so they have to upload a new one with the new dimension rules?

Thanks in advance! :D

Anyone? come on :( It should be easy for some "vbulletin veteran" ^^

Very hard to answer your question because you've said nothing about how you would be the imgur URL for each user. Is it stored in the database? If so where? And do you have a plugin to query the database for it?

As for number 2, why not just use CSS to make them all look the same size?

You could do the first with a custom profile field and have users input the imgur id and extension.

This is extremely silly, though.
